Ah yes, you're right. I don't know why but I made the mental shortcut that the mutation rate was about the DNA of cows / humans and not the flu virus.
The general point still holds : I am wary of the assumption of a constant mutation rate of the flu virus. It really facilitates the computation, but if the computation under this simplifying hypothesis leads to a consequence which contradict reality, I would interrogate this assumption.
It's surprising to have so few human cases considering the large number of cows infected if there is a human-compatible viron per cow.
Another cause of this discrepancy could also be that due to the large mutation rate, a non-negligible part of the virons are not viable / don't replicate well / ...
There are papers which show heterogeneity for influenza / RNA viruses but I don't really know if it's between the virus population (of the same kind of virus) or within the genome. And they are like a factor 4 or so in the papers I have seen. So maybe less relevant than expected.
Regarding the details, my lack of deep knowledge of the domain is limiting. But as a mathematician who had to modelize real phenomenon and adapt the model to handle the discrepancy between the model's conclusion and reality, that's the train of thought which comes naturally to mind.
I am no biologist but I thought it would be fun to give it a try. Hoping it's not too late to participate.
For the purpose of this experiment, I assumed everything written in sound scientific papers was right, as I had neither the time nor the knowledge to do a proper truth-check.
Here is what I found :
The fact that we see very few human cases compared to what we could expect for a virus which can become human-compatible with a single point mutation could be partially explained by the heterogeneity of the mutation rate over the genome:
- in this paper, a 1 to 100 ratio of mutation rate inside the human genome is mentioned : https://pubmed.ncbi.nlm.nih.gov/35218359/
There are known factors which hints at a low / large mutation rate for a sequence, so one could investigate further whether this would be the case for the "single point mutation" mentioned
-> you can divide the probability by 100 in the best case
A paper where they infect ferret with H5N1 and test how to mutate the genome to make it airborne:
- https://pmc.ncbi.nlm.nih.gov/articles/PMC4810786/
- "Four amino acid substitutions in the host receptor-binding protein hemagglutinin, and one in the polymerase complex protein basic polymerase 2, were consistently present in airborne-transmitted viruses."
As an alternative to tamiflu which can also be used in combination with it : favipiravir
- https://www.sciencedirect.com/science/article/pii/S0163725820300401, a 2020 paper about it
- licensed as an influenza drug in Japan
- when used in combination with tamiflu, a 2020 paper (with small sample size = 40) suggests that combining tamiflu with favipiravir improve significantly the efficiency
- as it has been envisioned as a drug against COVID, it's easy to find meta-analyses on the side-effects of this drug
- a huge problem with tamiflu is that the influenza viruses develop resistance to it. favipiavir does not seem to have this problem
I would like to highlight that the advice is sexist and not unisex as stated. All these steps for a guy to meet as many partners as they can in order to really find one which fit their goal, and the advice for the woman is only to actively pursue people they are attracted too ? If the goal was really for any person to meet the best partner for them, it would ensue that women, as rational agents, should also try to maximize their encounters with men, to maximize the chance to find a man who is a great fit to their preference. The advice given here for women (while helpful, I am all for expressing your interest to people you're interested in) would be optimal if the goal was to help the men they're interacting with find a good partner, not to help these women themselves.
Overall, this text has a bad vibe, I have the sense that this approach taken too literally and without concern on how the person you're considering to date would feel could easily lead to creepy behaviors and interactions. If you want to give dating advice to men (given the writing of this text, I would assume that's what you typically do), you would benefit from talking to women to get their perspective, reading feminist texts, queer ones even. Finding a good partner while making people you're interacting with having pleasant experiences is highly preferable than doing it at the cost making dozens of people uncomfortable or even feeling unsafe with your approach. The later is ethically questionable.
The discussion on the impact on false positive / false negatives would be more fair if you also discussed the negative impacts implementing bayesian punishment would have. For example, if you start giving small punishments for crimes with low credence of guilt, that would not be punished in the current system, this will add its lot of false positive.
I would not be confident it would be a good idea to implement this in our current justice systems. It may have a negative impact on people's faith in justice (is it deserved ? yeah ! is it good ? not sure) and my view of the justice system is that it's an essential part of society which is quite fragile as it relies in part on the lie that the justice system is fair and that it's decision is the truth. Plus, more generally, I don't think judges would handle the credences correctly, it's quite a difficult task to transform an heteregoneous and large set of proofs, among which testimonials, into a credence.
Thanks for the post ! I have tried doing EMDR by myself following these instructions after struggling to find a reliable EMDR therapist and it's definitely a new addendum to my therapeutic toolbox. It's great to process difficult events that happened in the past and the subsequent feelings.
In the link you refer to, there is a phase at the beginning where the therapist teaches self-care techniques to handle strong emotions (or they ensure that the patient already has such tools). This was lost in your post and I think it is important in order to avoid retraumatization and bad experiences. I felt confident trying the technique because I know how to soothe myself if needed and be present with my feelings, but I am pretty sure it would have been a scary or even maybe a painful experience otherwise.
