Question 1.1

Why do we know that the 10 percent myth is false?

Brain-damaged individuals demonstrate that when someone is shot in the head, there is not a 90 percent chance their brain will emerge unharmed. The large association areas in intelligent animals (such as humans) serve important purposes in processing and storing information. The whole brain is active as we think, feel, and act.

Question 1.2

The idea that most of us “only use 10 percent of our brain” is perhaps the greatest “neuromyth.” (This myth is often declared by those selling a strategy or product that will supposedly help us use the other 90 percent.) How did this myth arise?

In humans, the brain’s vast “association areas” sometimes produce little obvious response when electrically probed. This relative “silence” contributed to the false idea that most of our brain cells are unused.

Question about confidence

Recording

Eyewitnesses should be asked to state how confidence they are in their identification of the suspect.

The eyewitness should be told that the suspect may not be in the lineup or the photo array, and that the police will continue investigating even if the eyewitness does not select someone.

The eyewitness should be recorded—audiotape or videotape—when making any identification.

The other “suspects” in a lineup or photo array should look similar to the actual suspect.

The police officers who conduct the lineup or show an array of photos to an eyewitness do not know who the suspect is.
