Have We Evolved to Be Religious?

We humans have many varieties of religious experience. One of the most common is self-transcendence — a feeling becoming part of something larger, grander and nobler. Most people experience this at least a few times in their lives. When the self thins out and melts away, it not only feels good but can be thrilling.

It’s as though our minds contain a secret staircase taking us from an ordinary life up to something sacred and deeply interconnected, and the door to that staircase opens only on rare occasions. The world’s many religions have found a variety of ways to help people find and climb the staircase. Some religions employ meditation. Others use spinning, dancing and repetitive movements in combination with music. Some use natural drugs. Many secular people have used these methods too — think of the popularity of rave parties, which combine most of these techniques to produce feelings of “peace, love, unity and respect.” As the great French sociologist Emile Durkheim put it, we are “homo duplex,” or a two-level man.

The big question is, Why do our minds contain such a staircase? I believe it’s because there was a long period in human evolution during which it was adaptive to lose the self and merge with others. It wasn’t adaptive for individuals to do so, but it was adaptive for groups. As evolutionary biologists David Sloan Wilson and Edward O. Wilson have proposed, religiosity is a biological adaptation for binding groups together and helping them enter a mind-set of “one for all, all for one.” Groups that developed emotionally intense, binding religions were able, in the long run, to outcompete and outlast groups that were not so tightly bound.

If the human capacity for self-transcendence is an evolutionary adaptation, then the implications are profound. It suggests that religiosity may be a deep part of human nature. I don’t mean that we evolved to join gigantic organized religions — that kind of religion came along too recently. I mean that we evolved to see sacredness all around us and to join with others into teams that circle around sacred objects, people and ideas. This is why politics is so tribal. Politics is partly profane, it’s partly about self-interest. But politics is also about sacredness. It’s about joining with others to pursue moral ideals. It’s about the eternal struggle between good and evil, and we all believe we’re on the side of the good.

Most social scientists have assumed that religion is not an adaptation. They try to explain the rise of civilization using ideas about kinship (we can be nice to those who share our genes) and reciprocity (we can be nice to those who might return the favor some day). Cooperation with strangers that we’ll never see again is assumed to be an evolutionary “mistake.” But if you see religion as an adaptation that helps groups compete, then religions make a lot more sense.

This perspective also helps explains the persistent undercurrent of dissatisfaction in modern life. Ever since the Enlightenment, modern secular society has emphasized liberty and self-expression. We exult in our freedom, but sometimes we wonder: Is this all there is? What should I do with my life? What’s missing? What’s missing is that we are homo duplex, but only our first-floor, profane longings are being satisfied.

One great challenge of modern life is to find the staircase then to do something good and noble once you climb to the top. I see this desire in my students at the University of Virginia. They all want to find a cause or calling that they can throw themselves into. They’re all searching for their staircase. Most people long to become part of something larger. And this explains the extraordinary resonance of this simple metaphor conjured up nearly 400 years ago. “No man is an island entire of itself. Every man is a piece of the continent, a part of the main.”

This essay is adapted from the conclusion of a talk that Haidt gave at TED 2012.

The article refers to the human capacity for self-transcendence as an evolutionary adaptation and a deep part of human nature. The author may be romanticizing the herd instinct, which to me was the basis for say, our collective rampage in Iraq. 


  • Faith makes social groups stronger and confers an evolutionary advantage. 
Faith makes predatory leeches more powerful and confers an evolutionary guarantee of Mutually Assured Destruction. From the start, religion has been a pretext for leaching. The literal translation of Yahweh Shibboleth is "He is musters armies". He (or She, which could explain the need to speak unto Moses) is the original War Lord. The first God of War. All war is antisocial leaching.

Numbers 31 (KJV)
  • 1 And the Lord spake unto Moses, saying,
  • 2 Avenge the children of Israel of the Midianites: afterward shalt thou be gathered unto thy people.
  • 3 And Moses spake unto the people, saying, Arm some of yourselves unto the war, and let them go against the Midianites, and avenge the Lord of Midian.
Who is avenging whom? A ruthless battle fought by warrior soldiers against humans who prepared for Peace, probably because leaching and war is M.A.D.
  • 48 And the officers which were over thousands of the host, the captains of thousands, and captains of hundreds, came near unto Moses:
  • 49 And they said unto Moses, Thy servants have taken the sum of the men of war which are under our charge, and there lacketh not one man of us.
10,000 'men of war' wanted sex slaves (and it bears thinking about why, if one knows anything about female reproductive biology) went to 'war' against 200,000 of their betters who wanted Peace. They murdered them all without losing a single man because the Midianites were too sane to fight. 

The great religions became great because their demon god gives them a pretext to prepare for War and genocide. They slaughtered all superior civilisations and cultures who prepared for Peace. There's no evolutionary advantage to cannibalism. The human species is being Naturally Deselected off this planet. 

Happy Thanksgiving, leeches. 


Professors who can write intelligent-sounding things about topics they are not well-versed in should avoid contributing uncritical opinions to respected news sources.


Another answer would be that we're created to worship, so we're engineered to enjoy it
