MythBusters Season 4 Episode 8 Mind Control

In the eighth episode of season four of Mythbusters, titled "Mind Control," the team tests multiple myths surrounding the power of the mind on both cats and humans.

The first myth tested is whether or not cats can detect earthquakes before they occur. To test this, the team sets up a series of cameras and instruments to track the movements of the cats before, during, and after an earthquake simulation. The results are mixed, but the team ultimately concludes that while cats may be able to sense small tremors, they are not reliable indicators of earthquakes.

Next, the team tackles the myth that humans can control their heart rate and blood pressure using only their thoughts. To test this, each member of the team uses biofeedback equipment to monitor their physiological responses while attempting to lower their heart rate through meditation. While some members are successful in lowering their heart rates, the team concludes that this is likely due to relaxation techniques rather than direct control over the body's physiological responses.

The third myth tested is whether or not subliminal messages in advertising can convince people to purchase certain products. To test this, the team creates a mock ad with subliminal messaging and presents it to a focus group. While some participants report feeling influenced by the subliminal messaging, the team ultimately concludes that there is not enough evidence to support the effectiveness of subliminal messaging in advertising.

Finally, the team tests the myth that hypnosis can be used to force someone to commit a crime or reveal confidential information. To do this, the team employs a professional hypnotist to attempt to hypnotize Adam and Jamie, who then undergo a series of tests to see if they can be convinced to either commit a crime or reveal confidential information. While the hypnotist is able to put Adam and Jamie into a trance-like state, they both report feeling in control of their actions at all times and are not convinced to commit any crimes or divulge any classified information.

Overall, the team concludes that while the mind can be a powerful tool, the myths surrounding its capabilities are often exaggerated or unsupported by scientific evidence.
