What causes conspiracy theories to develop? Psychologists have found that in order to understand a major or unexpected event, people look for meaning in it, the why and how of the event. Unfortunately, accurate information may be scarce immediately after the event and the lack of information leads to rumors and guesses.
Legal scholars and Vermeule (200
describe what happens in their paper, Conspiracy Theories:
Whenever a bad event has occurred, rumors and speculation are inevitable. Most people are not able to know, on the basis of personal or direct knowledge, why an airplane crashed, or why a leader was assassinated, or why a terrorist attack succeeded. In the aftermath of such an event, numerous speculations will be offered, and some of them will likely point to some kind of conspiracy.
To some people, those speculations will seem plausible, perhaps because they provide a suitable outlet for outrage and blame, perhaps because the speculation fits well with other deeply rooted beliefs that they hold. Terrible events produce outrage, and when people are outraged, they are all the more likely to attribute those events to intentional action.”
This, and like some of you say, capitalism.
