  1. Neurodivergence is the state when someone's brain functions in a way that is in one or more ways, significantly different than typical. Normally it is used to describe individuals with Autism, ADHD, Dyslexia and a few other disorders - but when you take just the definition it could apply to other things as well. Does a brain with someone who is in 10th highest percentile in both Extraversion and Agreeableness significantly different from average? IMO it is
  2. The personality trait conscientousness involves being hard working and doing things that aren't intristically interesting. What motivates people to do that? Is the reward system active in highly conscientous people just as it is during pleasant things?
  3. I mean extreme scores of the Big Five traits. Someone who scores lets say in the 10th highest percentile in Extraversion and 20th percentile in Openness is not disabled but their needs and preferred lifestyle are very different compared to an average person and trying to squeeze them into mainstream society would be quite difficult.
  4. What do you think about the ideas of Jordan Peterson? More precisely the idea that history of human society is that of dialogue between conservatives and liberals and that if conservatives and liberals can agree on something, then it's likely a good thing to do. In other words too much conservatism is bad and too much liberalism is also bad
  5. Let's say you start with something simple like dandelions. You want dandelions that are 2x larger than normal. There are 10k people each of them grows 200 dandelions
  6. How fast can crops be bred for certain traits assuming we start with wild plants? Can 1% increse in average mass or speed of growth per decade be achieved if there are 10,000s or 100,000 of people breeding that crop and it is annual?
  7. Do you know whether cattails react well to organic fertilizer like dung or compost?
  8. Which regions of the Prefrontal Cortex underline response inhibition/stop signal tasks and why are they underactive in some people?
  9. 1. How far north does cattail grow? 2. I I put a great number of seeds in the ground without water, are there any chances that I get cattail growing on land?
  10. With US having lots of problems with student debt and such, do you think the free model of higher education like in Europe should be implemented/
  11. Amerindians have always lacked a proper draft/riding animal. Caribou could have filled that role.
  12. Do you think domesticated Caribou could be selectively bred to a size similar to that of horses and provide a viable alternative to horses in North America? Raindeer were domesticated and raindeer and caribou are practically the same.
  13. IF two human siblings have a child, what is the average risk of it having a genetic disorder?
  14. What exactly is this? I saw it refered to several times but no explanation as to what it is.
  15. Why are some people mostly interested in people in their closest vicinity like family and neighboors while others have a much wider circle of firnds/ Does Extraversion and Openness have something to do with this?
  16. Some people have naturally very low reward sensitivity and are less motivated by reward or punishment In case of neurotic disorders the goal is to strengthen activity in the Prefrontal Cortex and hippocampal neurogenesis with things such as ketamine, allopregnanolone or regular SSRIs even. How do we do the same with reward system?
  17. MBTI is not scientific, it was created by two women with no experience in psychometrics. Big 5 and HEXACO are created by professional psychologists and have been in use for several decades now but MBTI is much more used by businesses and is more popular.
  18. Humans do not have 100s or 1000s of personality traits. You may create a test with 100 traits but all or most of them will be variations of those 5. There is stuff that is not covered by the Big Five but could be added - Systemizing Quotient, Theory of Mind Quotient (i.e. cognitive empathy) and a few things
  19. It is mostly academic psychologists that use it for the purpose of research. If we can use science to describe properties of squares and triangles, why not human personality?
  20. For determining people's peronality traits even in a rather rough and not comprehensive manner. At the root of the Big Five is the so called lexical hypothesis. A hypothesis that all important personality traits will be reflected in the language. A group of psychologists analyzed words describing human personality and came up with (IIRC) several dozen triats which was later narrowed down to 5 traits and 30 facets. It is by far the most widely used personality model in psychology and other popular ones like Alternative Big Five and HEXACO are basically variations of it. There is certain % of people whom the Big Five cannot deal with - stuff like Autism, Schizotypy/Schizoprenia do not map nicely into Big Five but the model is good enough to describe majority of personality variation in vast majority of normal people IIRC thriftiness is covered in the Agreeableness facet Industriousness and honesty under Agreeableness. Humor is also at least partially a function of certain facets of Extraversion and Agreeableness
  21. Do you think the tse tse fly might be the reson why civilization in Africa never developed to the same level as in Europe/ It carries deadly diseases that kill livestock like crazy. Therefore draft animals never took hold in Sub Saharan Africa, severely limiting amount of available power.
  22. Soviet/Russian war films are excellent
  23. Did any of you guys try to estimate what Big Five traits of some historical figures might have been? i have tried for Hitler - Neuroticism - above average, average/low on depression-anxiety, high on angry hostility, vulnerability and self consciousness - Extraversion - average or high, most probably moderately high - Openness - low. moderately above average on intellectual curiosity, below average on everything else Conscientousness - low. He was known for being lazy and could only work on few things that mattered to him, i.e. his political cause Agreeableness - low. Only good for a small group of people, a bastard for everyone else
