Abstract

Disagreeable individuals earn significantly more than agreeable people, especially men. The "agreeableness penalty" is real.

Correlation Data

Negative Correlation

Consensus: Well-documented. Judge et al. (2012) found disagreeable individuals earn ~18% more than agreeable peers.

Variable Y: Higher Income

Variable X: Low Agreeableness

Biological Mechanism

Willingness to compete, negotiate aggressively, and prioritize self-interest leads to better salary outcomes.

Scientific Explanation

Disagreeable people ask for raises, negotiate harder, are willing to appear "difficult," and prioritize their own advancement. They don't sacrifice salary for likability.

Real World Examples

Steve Jobs was famously disagreeable but achieved extraordinary results. Demanding negotiators consistently outperform accommodating ones.

Advisory Protocol

If highly agreeable: practice negotiation skills and advocacy for your own interests. You can be kind AND advocate for yourself.
