Faith In Humanity: The Light Triad Trait Of Trusting People

Faith in humanity is the belief that people are fundamentally good. Learn what the trait means, what research links it with, its risks and how it differs from naivety.

Faith in humanity is the belief that people are, at heart, good. Someone high in this trait gives others the benefit of the doubt, expects decency and is slow to assume bad motives. It is one of three traits in the Light Triad, the counterpart to the Dark Triad proposed by Scott Barry Kaufman and colleagues in 2019.

What The Trait Looks Like

People high in faith in humanity tend to:

  • Assume a late reply means someone is busy, not rude.
  • Forgive mistakes once someone apologises.
  • Expect strangers to help if asked.
  • Feel that the news overstates how bad people are.

People low in the trait expect others to be selfish and look for hidden agendas. That is not always wrong. But a strongly cynical view tends to be self-fulfilling: if you expect betrayal, you behave in ways that invite it.

What The Research Says

In the original Light Triad studies, faith in humanity correlated with:

  • Higher life satisfaction and a sense of meaning.
  • Empathy and compassion.
  • A “quiet ego”, meaning less need for self-promotion.
  • Lower scores on all three Dark Triad traits.

Related research supports the trait’s value. Studies by Olga Stavrova and Daniel Ehlebracht found that cynical distrust predicts lower income and worse health over time. Research on generalised trust links it with stronger communities and better cooperation.

Is the belief accurate? There is some evidence for it. In a 2019 field experiment by Alain Cohn and colleagues, “lost” wallets with money were returned more often than those without, across 40 countries, and most people surveyed predicted the opposite.

Frequently Asked Questions

Is faith in humanity the same as optimism?

They are related. Optimism is about expecting good outcomes in general; faith in humanity is specifically about trusting people’s character.

Can you lose faith in humanity?

Yes. Betrayal, trauma or long periods of negative news can lower it. It can also be rebuilt through positive experiences and community.

Is it risky to have high faith in humanity?

Slightly, if it overrides judgement. Pairing trust with boundaries keeps the benefits and limits the risks.
