Evidence does not become weaker because the conclusion makes you uncomfortable.

How a conclusion feels has nothing to do with how well it is supported. The evidence for something you would rather not accept is exactly as strong as the same evidence pointing somewhere pleasant, and your reluctance is not a counterargument. Nearly everyone applies a much stricter standard to findings they dislike, and does it without noticing.

When you find yourself picking at a study, a report, or an account, check whether you would be scrutinizing it this closely if it said what you hoped. If not, apply the same level of examination to the version you prefer. Symmetry of standards is most of what honest thinking requires.
