For a quarter of a century, researchers have been monitoring how our brains react to certain stimuli and how they process information. They have discovered that when the brain starts to get overloaded, it builds up a stubborn wall against sensational stimuli.

Modern humanity’s exposure to an ever-increasing amount of dramatic, violent, and sensational information, has forced the brain to resort to protecting itself.

About 20 years ago, the first signs of something unique happening inside the brain began to happen. Researchers discovered a strange phenomenon when they were studying the processing of stimuli and emotions of people in Germany.

Four thousand people took part in an experiment that extended over a couple of years. After the experiment, it was clear that the participants could not smell and taste as well as before. “In the department of smell and taste there was an extreme change,” says psychologist Henner Ertel from Munich. “The brain had developed a stimuli acceptance limit under which it refused to process any new stimulant” (emphasis added).i

Our sensitivity to stimuli reduces yearly by about 1%. The finer stimuli are filtered out of our consciousness, leaving more space for the coarser, stronger sensations. In fact, some psychologists believe that with each generation, we are losing the ability to process and accept more sensitive stimuli.
