For a long time, people who wrote on U.F.O.s have faced extra hurdles. Compared to those who write on other topics, authors on this topic are scrutinized more carefully for credentials and conflicting interests. The evidence they present is scrutinized much more carefully for detail, consistency, and potential bias and contamination, and much less likely alternative explanations are considered sufficient to reject such evidence. And even when they meet these higher standards, such authors still find it hard to gain much media attention.
As a matter of fact, despite some efforts, I am one of the little people.
