The drugs quickly activate the brain's reward system - a primitive neurological circuit buried beneath the cortex - and release dopamine. This neurotransmitter, which is central to pleasure and desire, sends a message to the brain: This is an important experience worth remembering. Through this, the body begins to ask for the sensation released by dopamine, causing the body to become addicted to the substance.
Alcohol, for example, acts on the nervous system by changing behavior and may even lead to addiction. Its consumption initially promotes disinhibition, relaxation and euphoria. In a second moment the depressing effects begin to appear, such as speech and reasoning difficulties, slow reflexes, worsening of motor coordination and behavioral alteration. A laughing alcoholic may suddenly turn into a violent subject. These combined effects can cause a large number of problems, such as domestic violence and traffic accidents, many of them with death or permanent disability.

The tendency to overestimate the accuracy of our knowledge and judgments is called <u>Overconfidence</u>.
The overconfidence effect is a well-established bias in which subjective confidence in one's judgment is consistently greater than objective accuracy, especially when confidence is relatively high. Overconfidence is an example of subjective probability misadjustment.
Throughout the research literature, overconfidence is defined in three different ways by him. About the placement of one's performance in relation to others. Excessive accuracy in expressing undue confidence in the accuracy of one's beliefs.
The most common way to study overconfidence is to ask how confident you are about a particular belief or answer you hold. The data show that confidence systematically outweighs accuracy.
