Which is an example if pseudoscience?

pseudoscience is used to describe something that may be reported or recorded as a product or real science, but actually there is no connection to proper scientific methodology and cannot be proven realistically. 

Some examples are Ancient Astronauts and Crop Circles, Astrology, and Polygraphs and Hypnosis.

I hope this helps :)

Pseudoscience includes things like theories, beliefs, or practices that have been or are considered scientific, but have no basis in scientific fact. This could mean they were disproved scientifically, can not be tested or lack evidence to support them.
