An experiment was conducted to identify the best time to make decisions. People were invited to participate in a laboratory survey. At first they were bombarded with questions: what color pen do you want? Black or blue? How to place a sheet of paper: vertically or horizontally? Do you want coffee? Two or three spoonfuls of sugar? With or without milk?
After that they were given a questionnaire with really important philosophical problems. As a result, most people could no longer cope with it, they needed a break. They feel tired after the adoption of the preceding series of small decisions. The conclusion from this experiment is that the important decisions need to be made early in the day.
