Final answer:
The Ted Talk on meditation indicates that our minds are lost in thought about 50% of the time, debunking the myth that we only use 10% of our brains.
Step-by-step explanation:
According to the Ted Talk on meditation, our minds are lost in thought approximately 50% of the time. This statistic challenges the common myth that we only use 10 percent of our brains and suggests that a significant portion of our mental activity is consumed by spontaneous thoughts. Notably, this concept is separate from the probabilistic interpretation of the quantum mechanical wave function, which does not relate to human cognitive processes or the frequency of mental thoughts.
