What are some examples of false assumptions?

While there are many examples of false assumptions, one example is "My science class is easy and my friend who is in chemistry says her class is so easy it is boring, so all science-oriented classes are easy." Another name for false assumptions is logical fallacies.

The following are some other examples of false assumptions.

• "I have a unicorn in my garage and it can't be proven that there isn't."
• "Sarah has red hair, Sarah has a lot of friends so, therefore, people with red hair have a lot of friends."
• "Fairies make flowers bloom, my garden does not have any flowers, so there are no fairies in my garden."
