There is no scientific evidence to support the claim that depressed people are more intelligent than those who are not depressed. While some studies have shown a correlation between high IQ and increased risk of mental illness, including depression, this does not mean that intelligence directly causes depression.
Instead, it's more likely that other factors contribute to both high intelligence and a higher risk of mental health issues. For instance, highly intelligent individuals may be more prone to overthinking and analyzing situations, leading to increased stress and anxiety, which can, in turn, contribute to depression.
It's important to remember that depression is a complex mental health condition with various contributing factors. Intelligence is just one of many factors that can play a role, and it's crucial to avoid making generalizations or attributing depression solely to intelligence.
