Doubter vs. skeptic: what’s the difference?

Doubter simply describes someone who has doubts or is unsure, without necessarily suggesting a systematic approach. Skeptic refers to someone who habitually questions the validity of something and often applies critical thinking, especially relating to topics like science or philosophy.
What they have in common
