If the environment gets cold, we will often shiver in order to:

• keep body temperature the same as the external temperature
• decrease body temperature
• increase body temperature
• regulate blood pressure

A organization posts an advertisement with a very "click-baity" title and image on a social media platform. The title and image draw in people to click on the ad. As the ad receives more views, the algorithm shows the ad to more people.

• Positive Feedback Loop

• Negative Feedback Loop
