Why We Trust Fools More Than Liars – New Research on Emotional Intelligence

Picture two colleagues telling you the exact same false statement. One knows it's a lie and says it anyway. The other has no idea whether it's true, and doesn't really care – they just want to sound confident. You instinctively relax around the second person. They're not a "liar," you tell yourself, so they seem less dangerous. New research confirms why we trust fools more than liars – and why this instinct quietly harms your ability to make good decisions.

What the Study Found

Psychologists at Wake Forest University ran three experiments on 800 students. They tested how people react to false claims from liars versus people who simply don't care about the truth (often called "bullshitters" in academic papers). The results, published in Current Psychology, show that identical false statements are rated as more believable when they come from a truth‑indifferent source than from a liar. The gap grows every time the claim is repeated – a classic "illusory truth effect."

But the most powerful finding came from timing. When researchers revealed that a source had lied after people already heard the claim, belief in the false information dropped. But when they revealed the source simply didn't care about the truth, belief didn't change at all. We are wired to update our beliefs when we know we've been deceived, but we have no such reflex for someone who rambles on without caring what's true.

How This Hurts Your Emotional Intelligence

Emotional intelligence (EI) is your ability to understand and manage emotions – both your own and others'. It directly affects your job performance, relationships, and income. Research by psychologist Travis Bradberry shows that 90% of top performers have high EI, and high‑EI people earn about $29,000 more per year.

EI breaks down into four core skills:

• Self‑Awareness – Recognizing your own emotions
• Self‑Management – Controlling how you react
• Social Awareness – Reading other people's emotions and intentions
• Relationship Management – Using all the above to build strong connections

The new research on why we trust fools more than liars is a perfect example of a social awareness malfunction. You fall into a "motive trap": you judge someone's intentions instead of checking the facts. The moment you decide "they aren't trying to deceive me," your guard drops. You clear their character and then stop checking whether what they said is actually true.

The Two Questions You Must Ask

To read people well, you need to separate two questions:

• "Was this person malicious?"
• "Was what they said actually true?"

Most of us answer the first question and then assume the answer settles the second question. That's a mistake. When you slow down and ask both questions independently, you'll get a far more accurate read on the situation – and protect yourself from being influenced by bullshitters.

How to Protect Yourself

Every time you catch yourself thinking, "Well, at least they weren't lying," pause. That's a red flag. Instead, focus on the content of what they said. Is it true? Can you verify it? Let the accuracy of the claim – not the perceived honesty of the person – guide your beliefs.

To sharpen your social awareness, psychologists recommend taking a validated emotional intelligence self‑assessment. It's a simple way to see where you stand and where you can improve. Because when you understand why we trust fools more than liars, you can start making smarter, more informed decisions every day.
