👉 Overcleanness is a concept in psychology that refers to an individual's tendency to perceive or experience something as being greater than it actually is. In other words, someone who feels overcleened may interpret a situation or event as being much larger than it actually is. This can be particularly noticeable when dealing with large numbers of people or objects, where the perception of "overcleness" can lead individuals to perceive the total value of the group as being greater than it really is.
