"We" aren't..but it seems like many people are..and it's being encouraged too.
Intriguing question and interesting discussion but I have to disagree that 100 years ago children had less knowledge because they left school at 14. My Dad was born in1905 and left school at 14 and adjusting for the different type of knowledge between then and now it seems to me that those who left school at 14 were better educated in comparison with young people today leaving school at 18 often unable to read and write properly and innumerate. But on a different tack this morning it crossed my mind what the effect on society would be if duelling was legalised. As women can learn to shoot as good as men I imagine the treatment of women would improve considerably. It would also be a strong inducement for better manners. Might iron out a few class inequalities too. Increase the death rate which we need and being despatched by a clean shot is a lot better than being mashed in a car crash or dying slowly of cancer. Would also get rid of a few useless hotheads and reinforce the virtue of maturity. And no. I am not a fascist.
We're definitely devolving when it comes to communication.
What's with touch screens and heated extremities? We are still evolving I think usually.
Natural selection is kind of not well understood, and not least that it's an historical term, not current. We're all evolving, inevitably.
Compare now with 100 years ago. As said before, there are no good old days. These are it. IQ and levels of intelligence and education are far higher. IQ is more shaped too by environmental factors. There's no"natural selection" for human beings - it's an out-moded term from the 19th/early 20th century
If you look back, you'll see what was known was less than now, and many didn't even go to school or left aged 12-14. Perhaps now ignorance is more noticeable than before, but I doubt ignorance levels are higher than 100 years ago. Short-cuts, having access to knowledge and knowing how to access it aren't bad things. And, use of technology increases thinking. The abacus was technology, and now it's the computer. Maybe take a look at Mind in Society, by Vygotsky.
Sure, OK. However. we're also stronger and bigger too. Genes always interact with an environment, and it's the environment that will determine those genes the come into play and be created. So behaviour, diet and medicine are mediating factors. You are perhaps unnecessarily pessimistic? If I had a genetic disorder, I know when I'd want to be alive - and it would be now, not 100 years ago :)
True enough there are negative trends (obesity, heart disease, deforestation to name a few), but many opposing positive trends too (advances in medicine, health education, protests).
