懐疑 (かいぎ) is more abstract and formal, often used in written or intellectual contexts. 疑い (うたがい) is a general term for doubt or suspicion and is common in everyday speech.
Using 懐疑主義 in casual conversation may sound overly academic. Instead, use phrases like 疑わしいと思う or 半信半疑 to express scepticism naturally.
