Who says so? (Do they have an axe to grind?) How do they know? (Do they have the resources to know the facts?) What's missing? (Do they give us a complete picture?) Did someone change the subject? (Do they offer us the right answer to the wrong problem?) Does it make sense? (Is their conclusion logical and consistent with what we already know?)
=== Misinterpretation: correlation ===
The concept of correlation is particularly noteworthy for the potential confusion it can cause. Statistical analysis of a data set often reveals that two variables (properties) of the population under consideration tend to vary together, as if they were connected. For example, a study of annual income that also looks at age of death, might find that poor people tend to have shorter lives than affluent people. The two variables are said to be correlated; however, they may or may not be the cause of one another. The correlation phenomena could be caused by a third, previously unconsidered phenomenon, called a lurking variable or confounding variable. For this reason, there is no way to immediately infer the existence of a causal relationship between the two variables.

"The use of p values for nearly a century [since 1925] to determine statistical significance of experimental results has contributed to an illusion of certainty and [to] reproducibility crises in many scientific fields. There is growing determination to reform statistical analysis...
