16. Truth Serum
- Chances We’ll See It: Medium
Despite what many might assume, “the truth serum” was just a case of one of the more interesting science fiction inventions not being possible. Supposedly, it is able to make you tell the truth whether you want to or not. However, despite what you might be thinking, it does not exist. At least, it doesn’t in the way you might be thinking.

We do have some things that help with suggesting or pulling out information such as hypnosis. However, we also have drugs like sodium amytal and sodium thiopental. They are psychoactive drugs that help with getting out information by tricking the mind but they do not operate like the truth serum you know from science fiction.
