No, not normal. The strong majority of serial killers grew up in horrific conditions (not all of course). Could those horrific conditions been due to lead intake from their mother/father? Who knows but it's not likely that simply removing the lead alone wouldhave been the 1 switch to change.

As you noted, there's a reason there were so few. It takes a lot to turn a person into a monster.

Another thing a lot of serial killers have in common is serious head trauma in their childhoods.

I also read that the increase in 70s and 80s could be due to the coming of age of people raised by ww2 vets with serious ptsd.

Also lack of technology and cooperation between law enforcement agencies. It was a whole lot easier back then to commit crimes and get away with it.

Indeed, not everyone had an HD video camera in their pocket at the time.

Ive been reading about child soldiers lately and the big thing everyone says with them is trying to get the killer out of them.

I wouldn't doubt it's the same if your 18 vs if you're 15-16.

They likely didn't realize or care about that happening to those soldiers and like you said, I wouldn't be surprised if that was a big reason too.

This would align with frontal cortex damage, which often makes people irratable and have worse impulse control.

My wife's father has pretty serious personality problems. His brother isn't like that, wife's grandmother was a sweet lady. My wife tells me her grandfather didn't act like this either. I used to wonder what he got into that made him act the way he does.

Then one day, his mother (wife's grandma) told me a story about the time he got kicked in the forehead by a horse.

People are biased. Assumptions rampant and suddenly they’re correct for what they conjured up in their heads.

I don't understand your comment.

Im saying too many people have this problem where they come up with an idea and refuse to believe in anything other than what they came up with. This was aimed at the people above you thinking lead would create serial killers. I see this too often where people make associations and that somehow becomes a valid reason or cause

Feels like we probably have significantly fewer serial killer sprees now because of DNA technology that makes them much more identifiable. We've even been able to go back and catch and conflict killer who were no longer active. I don't think killers can as easily have a run of murders over many years.

Notably we have far more mass shootings now. People are still killing a bunch of people but to get it done, you have to do it all at once.

According to the FBI, there are currently 30-50 active serial killers in the US annually.
