A new study published in the journal 'Intelligence' shares that if you tend to throw tantrums, you may not be as smart as you think you are.
According to CNET, Marcin Zajenkowski, one of the faculty members of the study, said "I was wondering whether people with high trait anger would manifest a bias in perception of their abilities and competence... Specifically, I tested whether high anger leads to positive intelligence illusion."
Their results? They say that individuals with high trait anger have a tendency to overestimate their abilities, and it's part of having narcissistic illusions.
This also confirms a theory I've had for many years: Anxiety and Overconfidence aren't on a sliding scale, but rather, are in a circular scale, right next to each other. People who are feeling anxiety or not confident in their endeavors will overachieve or overcompensate to look as if they've got it all together.
This makes sense to me, but if you need further documentation on the subject, feel free to check the full study by clicking here.
