What could have caused Fischer to Go Crazy?

Why would Fischer be "crazy"? Please do tell.
I hope you realize how dangerous it is to label as "crazy" anybody with controversial opinions. That's where freedom of speech goes to die.

There are lots of ways to go crazy. Drugs, syphilis, religion, tumors, mercury and other heavy metals, military service, nagging inlaws . . . people of all intelligence levels can wig out. If it happens to someone known for their thought processes and mental abilities it might be more easily noticed, but the occurrence might not necessarily be any more prevalent at higher levels of intelligence.
From a high level source,
Fischer went crazy due to dabbling in serious blindfold-chess training. Its been documented that >3-4 blindfold games per week, given a high level of concentration, will cause mental strain great enough to cause hallucinations, paranoia and anxiety attacks, and then cascade effect from there. Same thing happened to Pillsbury.

From a high level source,
unnamed, and therefore meaningless. Cite your source. Also, who determined the source was "high level"?

It was in his DNA. No doubt about that. The Fischer's were highly intelligent but "peculiar". Both his father and mother were "strange". However I would not use the word "crazy".

Chess.com is a remarkable website in that it attracts so many people who have medical degrees who can diagnose other people without so much as meeting them in person.

Once I read about his father being a German spy in WWII and he landen in the States from a German submarine soon after the WWII or something... I ever found the story so fantasist but being WWII so out of reality and common sense we never know for sure.
Later found this post: http://www.chess.com/article/view/who-was-fischers-father

the deeper you plunge yourself into understanding humanity and how the world they created operates, the crazier it would be for you not to go crazy

Fisher suffered brain damage from constant chronic stress brought upon by his "fight" with the "soviet machine."
I think that is quite "correct".

A highly analytical mind, combined raw power, and an obsessive personality can easily lead to a descent into madness.

Well yeah. It happened to Cantor and many others. You also need a disposition to become "crazy" and I have heard that his biological father had some mental problems. So it's possible he inherited it. However, the strain on his person during the Cold War and Chess Politics of the time might have contributed a lot to his mental desintegration. I have seen pictures of Robert Fischer, and he looked like someone who had been abused mentally and chemically.

As far as chess players go, Bobby Fischer was unbelievable. He was so smart that he managed to dominate the game at his time. I don't understand how someone that intelligent and creative can go crazy, I feel like at a certain point, your intelligence becomes so high that your ability to critically think about any type of problems such as relationships, drama, anger, would allow you to find the right answer to any problem a certain percentage of time. Therefore, rendering a crazy 'ceiling'.
Apparently not with Fischer, what do other people think about this?
you've been on chess.com for over 2 years. i'm embarrassed for you that you've started this thread.

How DARE you start this most outrageous of threads in this most sacred of places? Do you not realize there are people who think they own this this forum and for whom this is their whole world? The first thing you need to realize is that you don't post anything without clearing it with the forum police who have been here for years. Before studying the history of chess,you should study the history of this forum and all the right openings and idioms and strategies, lest you be beaten to a pulp with a wet noodle by the flaming forum Nazis.
