  Sorry, that was overly provocative and arguably unjustifiably personal. I apologize. The point is that the statistics do not back up many fears. > And why did you pick "Assault by sharp object: 1,805" instead of "Assault by firearm: 10,801" or just "Assault: 16,765"? The example was a 'stabbing rampage', that was specifically to try and find the number of knife attacks in the US resulting in fatality, and out of those number where someone is randomly attacking people in public. Overall, we are still dealing with pretty small numbers whether it's 1 vs 5 or 1 vs 50 (50x improved chance of winning the lottery is still nearly negligible odds). In the case of knife attack, based on these numbers, it would be at most 1 in 5. The ultimate point is the statistics do not back up many of these fears. For example in response to an actual knife rampage I observed a lot of chatter about getting a concealed carry permit etc. These same statistics show that assault by firearm is way more likely than by knife, and having more guns around is more likely to have examples where they are used. Hence, the irrational fear of a knife rampage is prompting people to carry a gun, which then dramatically increases the chance of an accidental shooting in their own household, suicide, and/or assault where that person gets into a confrontation they could have walked away from but instead had road rage and shot someone else. Household, accidental shootings are relatively common, and suicide is exceptionally common, yet all that seems like less risks for firearm possession compared to needing the firearm to actually protect yourself from a knife attack, which is at most 5 times more likely than slipping and drowning in your own bathtub. In the case of a bathtub, it's common and does not have the same confirmation bias we get from headlines of rampages, yet it poses a fairly similar danger to you as someone going on a knife rampage.

    > The point is that the statistics do not back up many fears There is a saying, Lies, Damn Lies and Statistics. Or "tell me what you want the conclusion to be and I'll tell you what statistical method to apply to the data". Also known as "torturing the data". In the case of bathtub fatality, the majority of them are either very young or very old (kind of like covid): > Drowning occurred most often in a bath tub for persons under 1 year of age and for adults aged 85 and over https://www.cdc.gov/nchs/products/databriefs/db149.htm https://www.cdc.gov/nchs/products/databriefs/db149.htm If you adjust for age, that will make the bathtub/knife odds even worse. But on a more meta level, how do you feel about Nassim Taleb. My sense is that you don't like him, because he talks a lot about so called "irrational logic of fearing terrorists more than bathtubs", and he calls this behaviour extremely rational. https://twitter.com/nntaleb/status/832234355552559104 https://twitter.com/nntaleb/status/832234355552559104

      I do not know much about Nassim Taleb. According to the wiki article on him his main thesis is that societies are more robust when they plan for and can handle black swan events. Please let me know if that is an incorrect impression. To me that sounds somewhat different from irrational rational fears and also as somewhat reasonable. Irrational rational fear attributes greater danger to an unlikely event due to ignorance of how unlikely that event is. While Nassim Taleb's thesis (AFAIK) acknowledges the events are extremely unlikely but posits a system is more robust if such events can be handled. That seems to make some sense to me, but I would be concerned if such counter measures become prohibitive. For example, I suspect we no longer need to restrict knives on airplanes. No plane is ever again going to be hijacked with just a knife. We should though continue screening for bombs and plastic explosives, an attacker would be more likely and be more interested to depressurize the cabin and try to crash the plane and kill those onboard via a bomb than to hijack it (where everyone now knows they should rush a hijacker no matter the cost). A good analogy, a computer system that can handle errors that occur in 0.001% of cases is more robust than one that cannot. Particularly with large numbers thrown at it. The contra-point though is that real life is not large numbers, worrying more about a 0.001% probability compared to a 0.1% probability is generally misguided, particularly when a person believes that 0.001% probability is more like 10%. Though, that is where conditional probability kicks in and here is why I agree regarding "damn lies and statistics". Hence, even if the odds are 1 vs 500 or 1 vs 5000, these are all negligibly frequent events for the average person. Though, if you are over 85, in a bathtub, perhaps on some new medication, recently recovered from a surgery, and there is nobody else at home, then I would suspect odds of dying in that bathtub are far greater than they would be otherwise. As another example, it's kinda the same for Texas Hold'em, the odds of a 4 of a kind are generally low - but if the first 3 flop cards are all the same rank, the odds of someone having a 4 of a kind suddenly become reasonably quite good. So, I think the interesting conversation is around conditional odds and when as humans we accurately recognize those conditions. For example, many cyclists ride to the extreme right of roads fearing getting hit from behind. The statistics for that do not support that behavior, it's really rare for a driver to hit a cyclist from behind ("eyes on the road"). It turns out the majority of those kinds of collisions occur at night and when the cyclist has no lights on their bicycle. Meanwhile that misconception of the danger puts the cyclist in a more dangerous location, the further to the edge of the road the less visible from turning traffic (the real danger to cyclists), greater danger from road debris, pot holes, bad pavement, and getting doored and pedestrians popping out from between cars and getting doored (tl;dr, it's much safer for a cyclist to be a couple feet into the lane than immediately adjacent the gutter). Though the irrational rational fear has that person riding next to the gutter, putting them in greater overall danger.
