“Humans have a 'fight or flight' response, but no 'freeze' response.”

The idea that humans respond to danger solely with a "fight or flight" mechanism is a pervasive misconception. This dualistic view, popularized by early 20th-century physiologist Walter Cannon, describes the body's preparation for either confronting a threat or escaping it. The concept became widely recognized and ingrained in common understanding, often overshadowing other, equally vital, defensive reactions. The dramatic and active nature of fighting or fleeing made these responses easily observable and understandable, leading to their prominent place in popular culture and initial scientific models.

However, scientific understanding has evolved to recognize a more comprehensive range of responses. Humans and many other animals also exhibit a "freeze" response, which is a state of attentive immobility when faced with a perceived threat. This can involve becoming completely still, reducing heart rate, and heightened awareness of surroundings. Far from being a failure to react, freezing is an adaptive survival strategy. It can help an individual avoid detection by a predator, buy time to assess the situation for the best course of action, or even prepare for a subsequent fight or flight. This response is rooted in evolutionary mechanisms and is an involuntary behavior, engaging automatically when fighting or fleeing might not be viable.

The common belief that "fight or flight" are our only options likely stems from the historical emphasis on these two reactions in early research and their straightforward interpretation. The "freeze" response, being less outwardly dynamic, may have been less studied or simply not given the same prominence in educational and popular discourse. Furthermore, the initial focus of much stress research on male subjects might have contributed to an incomplete understanding of the full spectrum of stress responses. Modern science now acknowledges the "fight, flight, or freeze" response as a more accurate representation of our complex physiological and psychological reactions to danger.
