A false premise is an incorrect assumption that forms the basis of an argument and makes it logically unsound. For example, in the argument “all birds can fly, and penguins can’t fly, so penguins aren’t birds”, the assumption that “all birds can fly” is a false premise (since some birds can’t fly).| Effectiviology

A snuck premise is a controversial and unsupported assumption that someone includes in their argument as if it’s necessarily true. For example, if someone says “the problem with this immoral law is that it will have negative consequences”, the premise that the law is immoral can be considered snuck, if it’s controversial and unsupported by evidence.| Effectiviology
