How smart were we back in the olden days?
You're probably familiar with the Flynn Effect, which suggests that people gained about 3 points of IQ per decade over a period of 50 years during the 20th century. That's about 15 points total. This suggests that before World War II we were all roaming around with average IQs of about 85—which doesn't really seem plausible, does it? That's a fairly dimwitted average.
But I was reminded of this watching Jeopardy last night, which had a question about Hercules and Atlas. You remember the story. Atlas has been condemned to hold up the earth for all eternity when Hercules drops by to ask for a favor: He'll hold up the earth for a while if Atlas will steal some golden apples for him. Atlas does, but then tells Hercules he's going to take off and let him handle the job of holding up the earth. Hercules, sly dog that he is, agrees, but asks Atlas to hold up the world for a moment so he can put some padding on his shoulders. Atlas stupidly agrees, and Hercules heads off with the golden apples.
Here's the thing: this is presented as a clever trick, but in fact it's not something that would fool a five year old. How dumb were the ancient Greeks to make up a story that was so obviously juvenile?
Then there's that whole Trojan horse thing. I mean, how dumb do you have to be to think that would work? And how gullible do you have to be to fall for it? Odysseus got quite a reputation for shrewdness for coming up with it.
The first time this question of historical doltishness occurred to me was a couple of decades ago, when I was reading The Three Musketeers. I don't remember the details, but I do remember that it featured some really dumb behavior that wasn't presented as especially dumb. What kind of people were these? I thought.
I have nothing to say to wrap this up. I just wonder. Obviously there were lots of smart people in days of yore. But on average, were people badly dimwitted compared to today?
I don't know. But I remember also reading once that since water wasn't especially healthy back before public sanitation, it was common to drink only beer or watered wine (the alcohol killed the germs). So everyone was sort of mildly tipsy all the time, which might also explain things. Maybe the Flynn effect is just because we don't drink as much as we used to right before taking intelligence tests?
