Not based on scientific methods or principles; often relying on beliefs or intuition instead of evidence.
Many people believe in nonscientific explanations for natural phenomena.
Nonscientific → It is formed from "non-" (meaning not) and "scientific" (from Latin "scientificus", meaning pertaining to knowledge). The word "nonscientific" means not pertaining to or based on scientific knowledge.
Think of 'non-' meaning not, and 'scientific' relating to knowledge — so nonscientific refers to something that is not based on scientific knowledge.
