They are happier (because it's much easier - takes no effort at thinking and reasoning) to rely on what others in their circle of friends tell them about subjects like that. And that is also one of the basic reasons why conspiracy theories often take such deep roots. "The blind leading the blind" is very much a fact of life.
The following is an example of why someone might believe in a conspiracy theory. I don't know if Light was speaking about all conspiracies or not, so this is not a direct response to him personally. I believe it is a 'he', anyway!
I am extremely unhappy about the fact that a greater and more intensive effort was not made to locate the missing pieces of very important medical evidence in this case, which I pointed out back in the summer of 1972. Not that I was the first to learn of this, but amazingly, nobody had made that public disclosure prior to that time. I have raised same questions concerning the head wound and the possibility, albeit remote, of a second shot fired in synchronized fashion from the right side or the lower right rear, synchronized with the head shot that struck the President in the back of the head. And this is related to a few pieces, a couple of pieces of evidence and, again, emphasizes the necessity of having the brain to examine. These are the major areas. There are, of course, numerous facets of all of these disagreements that are related to the so-called single-bullet theory.
The words of Dr. Cyril Wecht, well-known forensic pathologist, from an interview for the House Select Committee on Assassinations regarding the assassination of JFK. He was asked to explain his disagreement with a panel of experts who were re-examining the assassination.
I recall him, on a documentary aired numerous times on the History Channel, referring to the "accidental" disappearance of Kennedy's brain as gross negligence. He stated that that level of incompetence would never be tolerated in any normal investigation. And when you think about the nature of this murder (one of the most famous assassinations in the history of the United States) you will understand the anger displayed by Mr. Wecht during that documentary on the loss of an extremely important piece of evidence.
Testimony like that from people who are reknowned experts in their field is also an elementary piece of what forms a conspiracy theory. (well, not ALL conspiracies are as valid, so don't hang me high just yet!)
In order to truly call him a certified blind man leading blind people, you'd have to be able to see better than him as regards his profession.
Dr. Wecht was at one time president of the American Academy of Forensic Science, one of several credentials to his name.
Curiously, a man who runs an anti-conspiracy website said of Cyril Wecht:
Wecht is a competent forensic pathologist where the Kennedy assassination is not involved. Is a person's competence so selective?
Incidentally, this is a tactic that is sometimes used by skeptics of the professional and armchair varieties: using credentials and PhDs and science as a weapon to clobber misguided believers and kooks, UNTIL it undermines your agenda. And then we have statements like the above, noting his expertise in ALL applications of his field EXCEPT this particular instance.
This re-examination of evidence also uncovered an audio recording made during that time which revealed, with almost 100% certainty, that there were four shots, one of them coming from the front.
Actually, if I'm not mistaken, much more recent analysis has uncovered what may be even more shots. Dunno for sure!
This is not a statement of any position I have regarding what is the highest-profile (and some would definitely say unsolved) murder case of the 20th century!!! This is merely stating other people's opinions, who know far more about it than myself.
I only used this example as a reminder that conspiracy theories can be supported by "expert" testimony and true scientific rationalism; they're not all die-hard kooks with gray matter falling out their "itching ears".
