”“PS "They" is plural. So we are still missing a singular pronoun that is not awkward for "her/his" etc. "Han" in Finnish works fine. Some people have already figured it out.
+1"Two things are infinite: the universe and human stupidity; and I'm not sure about the universe." ― Albert Einstein
Isaac Asimov: 'The saddest aspect of life right now is that science gathers knowledge faster than society gathers wisdom.', 'Never let your sense of morals prevent you from doing what is right.', and 'In life, unlike chess, the game continues after checkmate.'
I also disagree with your assertion that Mark Twain wasn't a genius. I would hold that he probably was in his understanding of human nature. Oh and he was friends with Nicola Tesla. Not that this means anything in particular but it causes one to ponder the nature of the company one keeps.
Questioning the integrity of the members of the scientific community does not equate with remaining a Neanderthal. In all of society we must question and challenge for the sake of finding the gems of true knowledge. How we feel about something has no bearing on reality. In the engineering group I worked in, the mantra was "show us the data". Keeping in mind that data was vetted carefully and questioned as best we could. Published data and statistics were often found to be corrupted by greed and vainglory, with careers and promotions being the driving force.
I never said 'all scientists' I said "some". So kindly refrain from straw man arguments. My concern is derived from personal experience with corruption in the sciences associated with industry. Oh, I grew up with a phd. father, so I am familiar with academia. Not impressed with the current product in general. I believe there has been a general decline in education from bottom to top with far too much emphasis on massaging the ego of students and not enough teaching on moral logic or how to determine sound reasoning. I am very concerned about the prevalence of narcissism I see in society. This is really bad for science.
There are many conscientious people going about their careers who truly love their respective vocations. This doesn't mean they are always right. Sincerity doesn't equate with truth or reality.
One of my friends is an amateur American Indian archeologist and flint knapper. I am familiar with the subject. Some of the artifacts we have found elicited an excited admiration for the maker in that the artifact showed a high level of skill.
Ignorance is not stupidity, rather it can be the launchpad of innovation if one applies themselves diligently with integrity, always remembering with humility, ones ignorance.
