Conventional wisdom, and many studies, hold that 40 hours of work per week are the optimum before exhaustion starts dragging your productivity down too much to be worth it. I read elsewhere that the optimum is even lower for creative work, namely 35 hours per week, though the sources I found don't all seem to agree.

In contrast, many tech companies in silicon valley demand (or 'encourage', which is the same thing in practice) much higher work times. 70 or 80 hours per week are sometimes treated as normal.

How can this be?

Are these companies simply wrong and are actually hurting themselves by overextending their human resources? Or does the 40-hour week have exceptions?

How high is the variance in how much time people can work? If only outliers are hired by such companies, that would explain the discrepancy. Another possibility is that this 40 hour limit simply does not apply if you are really into your work and 'in the flow'. However, as far as I understand it, the problem is a question of concentration, not motivation, so that doesn't make sense.

There are many articles on the internet arguing for both sides, but I find it hard to find ones that actually address these questions instead of just parroting the same generalized responses every time: Proponents of the 40 hour week cite studies that do not consider special cases, only averages (at least as far as I could find). Proponents of the 80 hour week claim that low work weeks are only for wage slaves without motivation, which reeks of bias and completely ignores that one's own subjective estimate of one's performance is not necessarily representative of one's actual performance.

Do you know of any studies that address these issues?

You'd expect Silicon Valley working practices to be less optimal than those in mature industries, because, well, the industries aren't mature. The companies are often run by people with minimal management experience, and the companies themselves are too short-lived to develop the kind of institutional memory that would be able to determine whether such policies were good or bad. Heck, most of SV still follows interview practices that have been actively shown to be useless, to the extent that they've been abandoned by the company that originated them (Microsoft). Success is too random for these things to be noticeable; the truth is that in SV, being 50% less efficient probably has negligible effects on your odds of success, because the success or failure of a given company is massively overdetermined (in one direction or the other) by other factors.

The only people in a position to figure this kind of thing out, and then act on that knowledge, are the venture capitalists - and they're a long way removed from the action (and anyone smart has already left the business since it's not a good way of making money). Eventually I'd expect VCs to start insisting that companies adopt 40-hour policies, but it's going to take a long time for the signal to emerge from the noise.

Can you elaborate? The impression I've gotten from multiple converging lines of evidence is that there are basically two kinds of VC firms: (1) a minority that actually know what they're doing, make money, and don't need any more investors and (2) the majority that exist because lots of rich people and institutions want to be invested in venture capital, can't get in on investing with the first group, and can't tell the two groups apart.

A similar pattern appears to occur in the hedge fund industry. In both cases, if you just look at the industry-wide stats, they look terrible, but that doesn't mean that Peter Thiel or George Soros aren't smart because they're still in the game.

On the one hand, yes. On the other hand I expect the working practices of mature industries to have been formed during the times of typewriters and three-ring binders.

Can you be more specific?

What do you think the factors that overdetermine a company's success are? I don't think I've heard of that many wildly successful companies in Silicon Valley with dysfunctional corporate cultures.

Bock said ... that learning ability was much more important indicator of whether someone would be a good fit for Google than I.Q.

I have limited trust in a source which says things like that.

Edited to add: More on Bock's learning ability:

For every job, though, the No. 1 thing we look for is general cognitive ability, and it’s not I.Q. It’s learning ability. It’s the ability to process on the fly. It’s the ability to pull together disparate bits of information.

Yeah, nope.

It's of course possible that this Bock guy knows what he's doing on the hiring front. But in these interviews he has no incentive to give Google's competitors coherent helpful information on how to hire people - and every incentive to send out obfuscated messages which might flatter the preconceptions of NYT readers.

I've pointed out in the past that in the Google context, range restriction is a problem (when everyone applying to Google is ultra-smart, smartness ceases to be a useful predictor), so Bock could be saying something true & interesting in picking out some other traits which vaguely sound like IQ but aren't (maybe 'processing speed'?), but then he or the writer are being very misleading (intentionally or unintentionally). I don't know which of these possibilities might be true.

Everyone who applies to Google is not ultra-smart. Far from it.

As a first-line interviewer, most people get rejected for being blatantly, horrifically incapable.

The perception that they are, unfortunately, causes many people who'd have a chance at acceptance to not even try. Anyone reading this, if you've thought about applying to Google and decided you don't have a chance, please think again! The opportunity costs are really low, and potentially negative; worst case you'll get a bit of interviewing experience.

Given that everyone who are hired are smart, gwerns point is valid.

Something to keep in mind is that a large organization (like Google) may have pretty decentralized hiring practices. Even if Engineering interviewers believe that "brainteaser" questions are a bad idea, that doesn't mean Sales or Finance agrees. And a site called "Business Insider" may care more about Sales or Finance than Engineering ....

I agree that it's surprising that (1) working long hours seems to have been found ineffective in academic studies and yet (2) businesses tend to want it. Aside from startups, I remark that the finance industry is notorious for extremely long working hours, and yet you'd have thought that (say) a hedge fund could benefit a lot from having its very expensive very smart people working more effectively if shorter hours would achieve that.

One possibility I've wondered about is that maybe it's about latency rather than bandwidth. In other words: If you're at work for shorter hours, then you may get more done but when someone else needs you -- especially if it might be someone else in a different timezone -- then they may have to wait a lot longer, and that may end up outweighing your greater individual productivity.

(I think I've seen something very like this offered as an explanation for investment banks' punishingly long hours: one of the things an i-bank's clients are paying a lot of money for is knowing that at any time they can call up the person who's trying to put together a deal, and discuss it with them. That means that those people need to be around for long hours, which means that the people doing analysis for them also need to be around for long hours. I have never worked in an investment bank and do not know how credible this is.)

Finance has a weird incentive structure. As my brother the stock trader explained it:

1) There is a practically infinite amount of work that any one group could be doing - there's always more data to be analyzed, companies to consider, etc., but there's diminishing returns to more work, because the best opportunities are exploited first and many kinds of financial activity are zero-sum competition over a finite pool of money. Hiring more people makes the total workload greater rather than dividing a fixed pile of work over more people. 2) Hiring someone takes money directly out of the pockets of their co-workers and the boss doing the hiring, so it's a last resort. Employee labor is the main expense, and pay and group "productivity" are tightly coupled: each group basically gets paid out of their own profits. If you're running a small group of traders - say, five people - and you decide to hire a sixth person, you and the other four people take a pay cut equal to that person's salary. (And because of diminishing returns, they don't make as much money per person as the smallest possible group that can do your kind of finance.) 3) Finance selects for people who want money more than time. People who can't devote just about every waking hour to work don't stay employed in finance very long - whether voluntarily or not. 4) Just about everyone in finance retires much earlier than in other professions. Once someone hits 40 or so they're usually burned out and leave the industry - they already have a huge pile of money, so they don't really need to keep working hundred hour weeks.

(1) Is true, just as it is true in scientific research, for example.

(2) Hiring people only if their expected contribution is greater than their expected cost is the baseline, standard, utterly normal practice everywhere.

(3) "People who can't devote just about every waking hour to work don't stay employed in finance very long" -- is false.

(4) "Once someone hits 40 or so they're usually burned out and leave the industry" -- is false.

I think you're confusing finance as an industry and small-scale, indie trading.

Since when did businesses behave according to perfect economic rationality, untainted by macho complexes or status displays/contests?

That means that those people need to be around for long hours, which means that the people doing analysis for them also need to be around for long hours.

Think what you might do if you were actually trying to make sure someone was awake and on-call for discussing a deal at all hours. To my mind, redundant staff or shift-work would function better than espresso-driven manias.

Whereas I've heard plenty about I-banking hours being a form of hazing, which makes perfect sense.

I think a lot of the finance industry overwork is outright about impairing employee judgement. Desensitization training - If a lot of what you do is abhorrent or just flat out nuts to the faculties of your recruits, work them until they are numb, and their sunk costs so high that quitting is no longer an option they can easily conceive of. Because they have no life other than the job. I also recall a highly hilarious study indicating that "skill" was essentially a nul factor in employee productivity in investment banking - so maybe it just flat out doesn't matter that the guy manning the desk is punch-drunk with sleep deprevation as long as he isn't so out of it he forgets to call frankfurt when the price of steel moves.

Do you have data on this? It's not something I've observed at any of the small number of Silicon Valley tech companies I've worked at.

It's tempting to think that because Silicon Valley is a center of growth for the economy, if things are done a certain way in Silicon Valley, that's the best way to do them. But Silicon Valley has lots of unusual stuff going on. Some things hurt, some things help, and on balance the unusual stuff seems to help more than it hurts. Also, different companies do things differently.

Are these companies simply wrong and are actually hurting themselves by overextending their human resources? Or does the 40-hour week have exceptions?

See this Quora question answered by people who ought to know: https://www.quora.com/What-are-the-optimal-working-hours-in-an-early-stage-startup-in-terms-of-hours-per-person-per-day-if-you-want-to-maximize-chances-of-success Possible sampling bias: people who are busy working long hours successfully didn't answer the question.

My suspicion is that 40+ hour workweeks are possible given the right kind of work and motivational structure: http://blog.nickwinter.net/the-120-hour-workweek-epic-coding-time-lapse Note that in the post, Nick Winter describes enjoying his work. My guess is that you should work on finding your work enjoyable and energizing before attempting to crank up the number of hours you work.

The claim that people can spend a ridiculous number of hours playing computer games is less controversial, and computer games often have significant intellectual content. If doing your work was hedonically similar to playing a computer game, I imagine that'd make it easier to work long hours. I've also found myself to be more creative and efficient when I find my work enjoyable--I work both harder and smarter.

I haven't solved the problem of finding my work enjoyable all the time, but if you don't have any ideas on making this possible, maybe try reflecting on your aversions and internal motivational structure. I've had success with listening to calm.com while working and trying to notice when more than one thing is competing for my attention and cutting it down to just one, for instance.

I would probably be able to get the same amount of work done in a 30 or even 20 hour week, given the amount of time wasted on meetings/email/waiting for data in an average office. Boss wouldn't want to pay me the same for a 20hr work week though.

Yes, unquestionably. We've known how human productivity works for over 100 years now. This knowledge has been "forgotten" due to the effects of tough, largely unprotected labor markets. If the guy at the next desk over stays an hour later than you every day, he'll look like he's working harder, so he'll be less likely to get laid off. Once you have multiple people thinking that way and no opposing structure to encourage cooperation, you get a classic status arms race.

Why Crunch Modes Doesn't Work: Six Lessons

Executive Summary

When used long-term, Crunch Mode slows development and creates more bugs when compared with 40-hour weeks.

More than a century of studies show that long-term useful worker output is maximized near a five-day, 40-hour workweek. Productivity drops immediately upon starting overtime and continues to drop until, at approximately eight 60-hour weeks, the total work done is the same as what would have been done in eight 40-hour weeks.

In the short term, working over 21 hours continuously is equivalent to being legally drunk. Longer periods of continuous work drastically reduce cognitive function and increase the chance of catastrophic error. In both the short- and long-term, reducing sleep hours as little as one hour nightly can result in a severe decrease in cognitive ability, sometimes without workers perceiving the decrease.


Managers decide to crunch because they want to be able to tell their bosses "I did everything I could." They crunch because they value the butts in the chairs more than the brains creating games. They crunch because they haven't really thought about the job being done or the people doing it. They crunch because they have learned only the importance of appearing to do their best to instead of really of doing their best. And they crunch because, back when they were programmers or artists or testers or assistant producers or associate producers, that was the way they were taught to get things done.

Another good article about the history of the 40-hour work week is Why We Have to Go Back to a 40-Hour Work Week to Keep Our Sanity on AlterNet. I recognize the political leaning of AlterNet may be offputting to some, so consider yourselves warned. I also don't necessarily endorse their theory that Asperger's Syndrome is to blame for the rise of overwork in Silicon Valley.

This, plus the known fact that most nerds can't cooperate. So even when some programmers start noticing the pattern, there is always some idiot who just cannot resist the opportunity to show everyone how smart he is by volunteering to work harder and longer, in worse environment, etc.

I also think that is a possibility, especially the first part, but so far I couldn't find any data to back this up.

As for drugs, I am not certain if boosting performance directly, as these drugs do, also affects the speed with which the brain recuperates from stress, which is the limiting factor in why 40 hour weeks are supposed to be good. I suspect that it will be difficult to find an unbiased study on this.

The value of having a 40 hour work week probably depends on what you do in the other hours of the day.

If you spent all the time outside of work relaxing you will get more productive than if you spend your time outside of work in highly stressful activities.

If you employ a computer programmer who spends 80 hours per week in front of a computer regardless of whether he has a 40 hour or 80 hour work week, it might make sense to ensure that all of those hours are spent of his work.

Opensource programming in his free time comes likely out of the same budget of mental resources.

I think silicon valley is an atypical example compared to the typical workforce. We are presumably talking about the high end of the technological productivity spectrum. And as we know the tails come apart. I'd guess that a lot of special people cluster in these jobs. Sure the tech companies try a lot to make work convenient - but I think a lot of the people working there are at least partly such highly productive because they invested lots of time into technology all their life. Working long ours in your calling is normal.

Look at me: I work 40 'normal' free-lance hours - more is not sustainable with 4 children. But many days I sit behind my PC 4 to 6 extra hours (often in thenight because I need less sleep). These are productive hours mostly. Coding, researching, learning, LW. Also on weekends. If a topic interests me I can keep up flow and concentration 16 hours straight. It is just for my family streak that I don't work insane business hours.

And I guess there are other people our there that are alike. Thus normal workplace lessons don't apply here.

True, and I suspect that this is the most likely explanation.

However, there is the problem that unless need-for-rest is actually negatively correlated with the type of intelligence that is needed in tech companies, they should still have the same averages over all their workers and therefore also have the same optimum of 40 hours per work, at least on average. Otherwise we would see the same trends in other kinds of industry.

Actually I just noticed that maybe this does happen in other industries as well and is just overreported in tech companies. Does anyone know something about this?

One argument for a longer work week:

You always have to do a fixed baseline of background work: Answering emails, meetings, filling out the forms for your company dental plan. Say that's 20 hours. So, a 60-hour week is not 50% more quality work-time (coding, etc.) than a 40-hour week, it is 100% more. Of course, it's best to arrange things to minimize the scut-work and focus on the highest-value effort.

Another argument: You want to avoid clock-watching. When you're hyped up, you work longer hours because you have the momentum and the urge to fix that one last problem. If you keep the work-day to 8 hours, it's hard to maintain that sense of drive.

Ideally, you maintain a sense of drive for the 8 hours (going over occasionally as needed) -- if you can manage that, it's the best combination.

These are reflective-decision arguments: Do X to make sure your mind focuses on certain goals. If we were reflectively consistent we wouldn't need to fool our own minds. As with other forms of rationality, you will do better if you can maintain reflective consistency than if you try to hack your way around it.

I don't care this much about maximizing output for my company, period. I've been careful to avoid more Hill and SF-type take-over-your-life jobs, because I get a lot out of my flexible time (writing a book, offering hospitality to others, seeing theatre, building things) that I would not get out of a job and that are difficult to trade money for.

Of course it's eminently reasonable for you (or anyone) not to care that much about maximizing output for their employer. However, employers might care about maximizing output, and if it turns out that long working hours (which are surely not optimal for the employees) aren't even good for the employers then that's pretty interesting, no?

And if that turned out to be true, and enough employers were convinced of it, then the range of options available to employees who don't want to work very long hours might increase a lot, which would also be interesting.

At least one of us is, I think, misunderstanding the other.

If in fact it's the case that employees with shorter working hours are (not only happy-feeling but) more productive for their employers, then sensible employers who come to understand this will give their employees shorter working hours. Not to make them feel happy, but to make them more productive.

Right, I'm saying that I do think it's possible that people working 60hr weeks might be more productive while being unhappier than the 40hr people. I don't trust that happiness and productivity are tightly correlated enough that an employer trying to get more of the latter out of me will help me out with the former.

Plus, there are a bunch of jobs that currently exist where the model is to extract a lot of productivity over 2-3 years while quashing an outside life and then to just hire a new crop of people when your current set burn out (TFA, I-banking, Hill jobs, etc).

I agree with all that. The only thing that puzzles me is that it looks as if you expect me not to, and I'm not sure how I gave that impression.

Perhaps I should make it explicit that my comment four upthread from this one wasn't in any way trying to suggest that employers can be relied on to do what's best for their employees, or to criticize you for your choice of jobs, or anything like that. I got the impression that you were suggesting that the question of what working hours lead to max productivity is a duly one or a boring one or an improper one, which I don't think it is even though employees should be thinking about other things besides productivity-maximization.

I think you can get more done by working longer hours...up to a point, and for limited amounts of time. Loss in productivity still means the total work output is going up. I think the break-even point is 60h / week.

In the videogame industry they have 80 hour work weeks all the time. They can get away with it because of employee turnover. If you burn out and quit, there's a line of people who'd be happy to take your place.

In other areas you still have managers and executives whose performance is evaluated on short-term results, so they will push the team to work hard, gain political points and move on.

This does not match my experience. I've seen very few people actually work 80 hours a week more than once even in a crunch cycle, and this matches an informal survey result which shows a distribution that peaks around 44 for normal work hours and 57 during crunch (page 21).

I also haven't experienced there being a line of people ready to take the place of turned over employees. Maybe there are many who would be happy to, but not nearly enough are talented enough to. The game industry has a market for employee talent just like any other, and it were ever the case that there was mass unemployment of qualified game developers, you would see those developers starting companies (as we are actually seeing recently).

I was surprised to see that, according to the same study above, the median tenure in the game industry is only 2 years, which you may have to take with the caveat it doesn't give details about how contractors and starving indies were meant to respond to the question. The median tenure for the entire U.S. economy is 4.4, but possibly the better comparison is for 25-34 year-olds, for whom the median is 3.0.

Yeah, my "80 hours" was an overstatement. Though maybe you can replace it with 60 and the message will still stand.

Indie game development isn't very profitable, and unemployed game developers can easily switch to normal software jobs instead. So for every one who starts their own indie thing, there's probably several more who leave the industry.

Yeah, leaving the industry is extremely common, but in my opinion not outcome-optimal for the employers who are driving their employees to extremes (or, more commonly, not encouraging normalcy). There are indeed young recruits who are willing to come in and spend huge amounts of time and effort on game projects, but there is huge variance in work quality in this group, such that the flipside of fast, positive work from a talented, unstable, young programmer is the risk of losing time on poor work from a weak, unstable, young programmer... with little way to know the difference. A senior engineer at 40 hours is substantially better than a junior engineer at 80 hours, and so companies probably should invest more to keep talent on future projects, which is of course hard to do when crunch rolls around on the current project.

I used to hear this saying around the industry: "When you're on the outside of games, it seems like nobody is looking to hire good talent. When you're on the inside, it seems like there's nobody talented applying."

Theory: It's all about signalling commitment to investors. A startup doesn't produce anything until it goes gold on it's product or gets bought out by a tech giant who then takes their product to completion. So it has no cash flow at all until hopefully at the end a dump truck full of money pulls up and buries everyone in wealth. Up until that day, what pays salaries - what keeps your company employees from starving to death in the street - is investors who believe in your idea and your product. And while working a forty hour week for the duration (and telling your workers to bloody well lay off the coding at home) would probably get you more, better and less buggy lines of code added to your product per week, that doesn't really help you if it looks to the people funding you like you are treating their investment as a nine to five.

"Sophisticated investors should know better"? Eh. The only skill that actually matters to the long term success of a startup investor is the ability to pick startups with good product ideas. The kind of investor who is an expert on productivity and employee management is most likely picking investments based on those factors in some other industry where that is what companies live or die by. Meaning, an industry which is mature.

This of course implies that the optimal strategy for a startup is to pick a good product idea and then just flat out lie through their teeth about how many hours of work they do per week. Does it sound very implausible that a lot of the silicon valley culture of overwork is fiction? And some of it is naive people trying to actually work as many hours as people more cynical about investor relations falsely claim to.

Do you know of any studies that address these issues?

In a sense, Silicon Valley is an ongoing study. Here you have a very large number of firms in a competitive environment, with low cost of entry, each firm looking for a productivity edge over their rivals. If holding the work-week down to 40 hours really made their employees more productive, don't you think you'd see lots of successful firms that have tried it?

And yes, I'm aware that there's signalling going on, but you'd still expect to see some successful firms that worked like that. Moreover, Silicon Valley firms go just the other way, doing everything they can to keep employees in the office by making it "fun" - that's the opposite of what a signalling explanation would predict, but strongly predicted by an "extra time in the office really is productive" theory.

Increasing the work week generally provides a short-term and more easily measured benefit (getting this project done sooner) but long-term and harder to measure harms (higher error rate and higher maintenance cost). Bean-counters are notoriously bad at trading off short-term benefit for long-term harm, and at preferring benefits which are easy to measure.

The problem is that during the industrial revolution it also took a long time because people caught on that 40 hours per week were more effective. It is really hard to reliably measure performance in the long term. Managers are discouraged from advocating a 40 hour work week since this flies in the face of the prevailing attitude. If they fail, they will almost definitely be fired since 'more work'->'more productivity' is the common sense answer, whether or not it is true. It would not be worth the risk for any individual manager to try this unless the order came from the top. Of course, this is not an argument in favor of the 40 hour week, it just shows that this could just as well be explained by a viral meme as by reasonable decisions.

This is part of the reason why I find it so hard to find any objective information on this.

But that's why I emphasised that Silicon Valley is full of startups, where there aren't risk-averse middle-managers trying to signal conformance to the prevailing attitude. Note too that there have been a wide variety of idiosyncratic founders. And because of the high turnover and survivorship bias, the startups we see today are biased towards the most long-term productive compared to all of those set up. Yet those companies behave in the exact opposite way to what your theory would predict.

If shorter work-weeks really are more productive, why don't we see successful companies using them? Your explanation makes sense in terms of a government bureaucracy; much less so in a startup hub.

A few ideas that occurred to me offhand:

-- long hours could be legitimately beneficial to startups, without being beneficial to companies in general

-- willingness to work long hours could be correlated with other traits that make the worker do well for he company, such as enthusiasm

-- related, willingness to work long hours may simply be correlated with other traits that lead the worker to work for a startup at all. For instance, young people without families are more willing to work long hours, and also more willing to take risky jobs such as at starups.

-- long hours could be part of a race towards the bottom, where any individual company that has its workers working longer hours does better, but if all the competing companies do it, they're all worse off than if nobody does it. This could happen if working long hours lets the company get a larger share of a finite resource (such as market share) without increasing the size of that resource

-- signalling competitions between individual workers could lead to the workers all working longer. The absence of middle managers only eliminates certain types of signalling, not all signalling

This isn't my theory. This is a theory that has been around for a hundred years and that practically every industry follows, apparently with great success. From what I have read, the 40 hour work week was not invented by the workers, but by the companies themselves, who realized that working people too hard drives down their output and that 40 hours per week is the sweet spot, according to productivity studies.

Then along comes silicon valley, with a completely different philosophy, and somehow that also works. I have no idea why, and that's what I made this thread to ask.

But Silicon Valley doesn't have a completely different philosophy from similar professions. Do doctors, lawyers, financiers, small businessmen, etc, typically work only 40 hours?

The 40-hour week you're talking about is a norm among factory workers, which is an entirely different type of labour.

Ok, I think it's becoming increasingly obvious you don't know how the 40 hour work week came to be, country by country. There were huge worker movements for decreasing the work hours. Many countries achieved these working conditions only eventually and by getting an appropriate labor reform law passed. And the stories behind such laws differed vastly depending on the country.

Because those countries also have lower labor costs, so executives can report that they're saving money on labor costs and their company's stock will go up. More cynically, international operations require more management (to keep on top of shipping issues and deal with different government circumstances in the different countries where operations are going on), and the managers who make such decisions may approve of an outcome where more is spent on management and less on labor. Most of the research I've heard of suggests that it is not because such relocations are overall more profitable; that's very rarely the case.

Remember that in issues of optimization, the question is always, "for what am I optimizing?" Startups have to scale as quickly as possible, or they'll run out of money or be supplanted by a competitor. A startup team pumps all their effort into a 2 to 5 year period, after which point they'll likely have achieved dominance in their market, been bought by a larger company, or failed. The game is short, and the payoff is bimodal (either very high or close-to nothing). Workign one's self into the ground for a few years to come out a millionaire maybe worth it.

In contrast, the employee at a typical large corporation wants to have his job (or a very similar one) and his salary (or one somewhat higher) for the next ten years and his employer similarly wants to have the continuous use of his labor.

A good rule of thumb is that if somthing seems insane or just wrong, consider the incentives involved. Many times it is actually insane, but just writing it off as so, doesn't help you understand it.

The 40 hour work week is a sweeping kind of a claim you wouldn't accept in any other context. It's like saying that to maximize the benefits of physical exercise, you shouldn't work out more than 10 hours a week, then proceeding to ignore the type of benefit you're looking for, anatomy, intensity, intervals, session length, fun, safety, individual talent etc.

I've seen frequent claims on LW that shorter hours are better for productivity, but very little data to back them up. Why don't people quote some studies so that we can scrutinize them to see if they actually say what people claim they say?

Serious (and not particularly considering myself part of any oppressed minority).

My experience is that addressing any group as "you people" is a near-infallible sign of hostility and contempt, with (not always but often) a side order of prejudice against whatever (political, religious, philosophical, social-class, ...) group "you people" might be part of.

Maybe my experience is atypical, or maybe yours is. You might want to do a bit of googling and see how the phrase is used and how it's perceived; if your impression on doing so accords with mine, you'll probably want to avoid using it when you don't want to signal hostility and contempt.

My mental autocompleter matches "you people" to things like "you people are all the same", "what the ---- is wrong with you people", etc.

(I note that urbandictionary.com's second definition for "you people" is "Blacks". For what it's worth, that isn't something I read into it -- though I see there's a similar suggestion on wiktionary, so maybe it isn't just urbandictionary.com being flaky.)

Since I'm not a native speaker my connotation-o-meter isn't always amazingly tuned. The issue is amplified when I think and type quickly. Since you're a native speaker I suppose your experience is more typical than mine, so I'll avoid "you peopleing" in the future unless I want to be extra cheeky.

"You guys" has absolutely none of the hostile/contemptuous feeling that "you people" has (at least for me). It's distinctly informal and (as you surmise) some people may interpret it as sexist.

I think I'd generally just say "you" and, if necessary, make it explicit what particular group I had in mind.

(Though ... it sounds as if you're talking about a use of the phrase with a rather different structure from the one we're discussing here: using it vocatively at the start of the sentence. "Hey, you people, listen up! Blah blah blah." or something like that.

I don't consider sleeping, cooking, eating or having sex free time, I consider them maintenance :)

Anyways my point is that most of the things you listed are definitely work for the brain, yet people don't think they affect your ability to be productive at work, since they're not something you're paid to do, which I don't think makes much sense.

If I mostly lived on Soylent or Mealsquares you'd have a point. Given that I often-ish go out to restaurants...

Well, not all the things on that list are the same: arguing that someone is wrong on the internet may drain my stamina almost as much as my paid job, but chatting over a beer occasionally glancing at the TV will drain my stamina almost as little as idly daydreaming -- possibly even less, depending on what I'm daydreaming about.

It totally does. First, there are these effects, and second, as I said, there are reasons why they're not something you're paid to do.

I'm not paid to listen to music I like but I might need to be paid to listen to music you like. Same deal with browsing your websites, reading your books and watching your movies.

If you're enjoying your work and having your cached selves do most of it, what's the big deal with long hours? How will they impact your productivity, if having ridiculously meticulous conversations on your favorite website doesn't?

Well, but the fact that it's the music I choose to listen to etc. means it doesn't drain my willpower as much. See also this.

If you're enjoying your work and having your cached selves do most of it,

Actually I meant the part of that post where if you pay someone to do something they'll enjoy doing it less.

what's the big deal with long hours?

Less time left to do the other things I mentioned? Certain things are terminal values; fiat currency isn't one of those. (Granted, I don't only do my current job for the cash, but I wouldn't spend as much time on it if I didn't need money.)

I'd like to note the sheer volume of people in the wider startup ecosystem generating reasons why they are smarter than science when this is brought up.

Let's investigate how little "evidence" they need before they completely ignore said research:

Many have the unmeasured, ridiculously unreliable anecdata "I produce amortized peak output working at a higher number of hours per week" (it's hard to tell that anyone has actually tried looking before claiming it, though: work 6 months at 40 hours/week and another 6 months at 70/hours a week). Why is this unreliable? Because working longer hours produces more artifacts of work, even when it produces less deliverable work. You have all these memories of being in an office, more emails, more comments in your bug trackers, etc. But how much work is done? Even if they did the experiment, there isn't a coherent way of measuring productivity of creative workers with n=1, almost all of us have quite a lot of variation in the complexity and familiarity of our work.

I know of only a couple people who have dramatically dropped their hours, and 100% of them are more productive (both more efficient and effective).

So there are people using almost no data (assuming they actually did measure themselves), and they claim to know better.

This is all to say, the startup ecosystem isn't thinking this through carefully. To the extent they end up being correct it will be largely coincidence.

Software programmers also frequently argue that it's impossible to measure software productivity.

As a software programmer myself I can say that's a pretty bizarre argument to make. Informally, almost all experts have a tool/language they feel gives them an advantage, and language holy wars are all about this topic. Doesn't mean they aren't just making it up, but worth considering that people saying "Node is better than Rails!" "TDD is better than !" can't simultaneously claim "There is no way to order different approaches by productivity".

But in fact, they is a way, and such measurement has been happening for long enough for us to develop reasonably accurate models of how it changes over time e.g. due to tools getting better, see Yannis' Law, which I confirmed myself a couple months ago (example task took me about five minutes not including when I read the description, so I'm within a factor of 2 of predictions -- I think we may need a better task in a decade or so, it's rapidly approaching weird task-size-minimums).

For these kinds of startups, everyone working is also an investor or owner or is otherwise hitched to the startup's survival. Working extra long hours can be a signal to investors in two ways. First, the workers believe in the idea enough to work double time. Second, the path to knowing whether the investment is worth another investment round will come sooner.
