13. What is the difference between pseudoscience and science?
Pseudoscience is not based on standard scientific research; it does not deal with testable questions, welcome critical review, or change its ideas when new discoveries are made. Science is the study of nature and is rooted in observations that are testable. Science welcomes critical review and changes its ideas when new discoveries are made.
