I don't think we are meaningfully different at all. The same types and groups of people and social structures all still exist today. I suppose the big difference is those of us who are well adjusted know that racism is not good, and tarot cards are meaningless woo woo. But there were also such skeptics back then too.
So I object to this weird article of faith every time it comes up, we can't have been exactly as sensible and exactly as clever in the past as we are today, it doesn't make any sense to say that. But it's somehow become right-on to say that it's so, as if denying it is a prejudice like timeism or something. It obviously matters to some world view, equality maybe?
Basically I think we have to pick a lane on whether we are talking biology, vs culture, vs knowledge and accumulated data.
But, I'm not saying that humans haven't learned anything, but that cognitively we haven't changed. A roman citizen has the exact same brain capacity to reason and adapt as we do today. There is zero separation from ancient human vs. modern human in that aspect.
You are conflating collective knowledge with individual human intelligence. That roman looking at bird entrails to predict the future was using the exact same pattern-recognition ability we use today to look at data visualizations, or trend graphs.
You could go back in time, steal an ancient roman baby, and raise them in today's year and they would be no different from you or I.
Compared to Roman times, we've had pretty big advances in nutrition, healthcare, education, and widespread middle class wealth. It's not unreasonable to infer that these would have an impact on cognitive ability similar to the effect they've had on life expectancy.
That being said, there's definitely a present-ist bias, as the McSweeney's article does a good job mocking. I do believe their best thinkers were as good as our best thinkers.
Maybe I need to spell this distinction out next time it comes up, which will be the next ancient history thread, probably. I guess the endless repetition of "they were just as smart as we were you know!" is in order to counteract an unstated idea that the ancients were some other species, like orangutans in bronze armor, I don't know. Maybe it's common to vaguely think that about them? But this gratuitous counter-point should be on a strictly genetic basis, or else you'd be accidentally denying that ideas improve.
If genuine, I'm puzzled. In the current world we have a tremendous amount of people who hold various superstitious beliefs as well as spend tremendous amount of time on their genealogy. And nepotism never went away. I agree those are "bad ideas", but don't see how they differentiate us from people 5k years ago?
I could point at all the self-help books that promise to improve the way you think, or Wikipedias list of fallacies, but I don't those are great examples either. It's frustrating that I can't make a simple point just because it needs more research. I hoped people would find better examples themselves.
I don't think your word "tremendous" works, I think superstition declined and values improved, but it's hard to nail this down for people who are keen to disagree. Does that include you? Why?
Outside of the "so mainstream and prevalent we don't even consider it" superstitions (which, remember, were all the historical ones we may dismiss now, thousand years later), we have horoscope and astrology, psychics, and people who think wearing same socks will help them on a winning streak, and everybody hesitant to talk about good or bad outcomes less they "jinx it". Maybe you're from Germany or Scandinavia and your daily experience is different?
But again, the thread started about biological differences and I will agree that there are little to none between ancient Egyptians and modern humans.
In terms of cultural values, sanctity of life, freedoms and poverty and lifestyle, I do think some things have improved. We can debate numbers as to how much.
Understand that as a Canadian, and not knowing where you're from, you unfortunately find me at a cynical time as we watch our southern neighbour work so very very hard to dismantle much of the progress we are discussing here very every effectively, so it's just difficult to put one's mind in historically optimistic mindset :-/
Romans had educated intellectuals who had some progressive and scientific ideas, and the less educated masses who had less progressive and educated ideas. This seems to describe today's world well. And we still LOVE to attack the "intellectual elite" for having progressive, scientific ideas.
