How about you answer these questions? Do you believe this is true on a scale of 1 to 5? 1 meaning not at all true. 2 meaning not likely to be true. 3 meaning may or may not be true equally. 4 meaning likely to be true. 5 meaning true.
What does the word BELIEVE mean? Have you ever looked it up? I have. One definition said, "To accept something as true without absolute proof." What is absolute proof? Doesn't the 'absolute' imply there are degrees of proof as in PROOF versus ABSOLUTE PROOF? There are not degrees of proof, there are degrees of probability. That definition is stupid. I came up with my own definition of BELIEVE. It is to accept something as true, or false, without sufficient evidence. Therefore belief is stupid by definition. The trouble is most people do not use the word SUSPECT very much. Suspecting and believing are two different things. The word suspect presumes that we are dealing with uncertain information and must evaluate evidence for probabilities. Isn't language fun? I neither believe nor disbelieve this business about lead and crime. I simply find it interesting. But if it is true then it is VERY IMPORTANT. Therefore I think it is important to find out for sure whether or not it is VERY IMPORTANT. Is that sufficiently clear? psik

Yet another deflection to avoid answering any questions by shifting to semantics about words I did not use. The one word I did use that you did not address was evidence. Why can’t you answer a simple question or two?
I know you dislike questions but I am terribly curious. What do you mean when you say, “Therefore I think it is important to find out for sure whether or not it is very important.”? I am sorry but that is anything but clear.

That's psikey's MO. Arguing with him is like trying to nail Jell-O to a wall.

Is English your first language? This is like talking to Siri about her first kiss.

English is my only language and I scored in the top 2% on the SAT though my math score what higher than the English. So what is the problem with what I said. Have you read any of the article about the Lead/Crime supposed relationship or not? psik

Yes, I read the article. <---------That is what an answer to a question looks like by the way.

Then if you read the article and you do not think there is any possibility of lead influencing those crime statistics then there is no reason for you to be interested in this thread. Right? psik

By your logoc, there is no reason for you to have started this thread.

Well we have a problem with what you call logic. I would have no way of knowing who would be interested or what they would think before I made the post. You are suggesting I should have made assumptions. I have found things interesting even when I decided they were nonsense. But you have to learn enough about it to make the decision. psik

One major problem with the article psikey linked is the NYPD has been underreporting crime stats, especially in the 1990s and 2000s. Kinda blows away the premise.

That is if you don't actually read the article or check any others.
Just this year, Tulane University researcher Howard Mielke published a paper with demographer Sammy Zahran on the correlation of lead and crime at the city level. They studied six US cities that had both good crime data and good lead data going back to the '50s, and they found a good fit in every single one. In fact, Mielke has even studied lead concentrations at the neighborhood level in New Orleans and shared his maps with the local police. "When they overlay them with crime maps," he told me, "they realize they match up."
