Skepticism, also spelled scepticism (from the Greek σκέπτομαι skeptomai, to search, to think about or look for), refers to a doubting attitude toward knowledge.

It doesn’t require evidence to be a skeptic, merely to question claims made by others. When only dogma and hearsay exist, a skeptic should draw no conclusions.

However, regarding Trump, based on past evidence of his behavior, a skeptic could assume a high probability of deception in some form.
