Can you explain this in detail a bit more?
I've been obsessed with intelligence for a minute now.
And to answer OP, I don't think we are any smarter but technology has made our attention span shot.
At a certain level, the more wealthy a nation gets...the more intelligent it population gets because they are healthier. Having a reasonably high standard of living for a population is a great way to increase average intelligence...well fluid intelligence.
There are two types of intelligence, fluid intelligence and crystallized intelligence.
Intelligence is simply the ability to learn and apply information, at the most basic level.
Fluid intelligence is the ability to learn and solve problems
Then crystallized intelligence is the ability to recall that information and put it to use.
Fluid intelligence is more genetic based. Actually your intelligence is majority genetic...unless you are born in deplorable conditions...like Afghanistan.
But it is important to note...
That the world is more secure today and safer today than it has ever been...yet the average intelligence of human beings is going down....
And that is because...people with high intelligence...on average globally...live in nations with high standards of living...and they don't have as many children than less intelligent people...
Then also...people are immigrating to high intelligence, high standard of living countries...yet these immigrants come from low intelligent, low standard living of countries...full of young people...meaning that these people reproduce like rabbits
Basically...we are heading into a new dark age...
