There isn't any scientific evidence to support the claim that people with lower IQs cry more than those with average or above-average IQs. IQ (intelligence quotient) is a measure of cognitive abilities and doesn't have a direct correlation with emotional expression or crying frequency.
Crying is a natural emotional response that varies from person to person and can be influenced by a wide range of factors such as personality, temperament, life experiences, upbringing, mental health, and coping mechanisms. These factors can affect how individuals process and express their emotions, including sadness, frustration, or joy, which may lead to crying.
It is essential to avoid making assumptions or generalizations about an individual's emotional tendencies based on their IQ level or any other single characteristic. Emotional expression is complex and varies greatly among individuals regardless of their cognitive abilities. It's important to treat each person with empathy and understanding, recognizing that everyone has their unique ways of coping with emotions.
