5 Reasons Why People Believe in God

Dr. Thomas Swan has a PhD in psychology from the University of Otago. He specializes in the cognitive and evolutionary study of religion.

Our minds evolved in a way that makes belief in gods especially appealing.

The Evolutionary Psychology of Religious Belief

In each civilization spanning the human epoch, a propensity for ascribing the unknown to the work of gods can be observed. The inevitable contradictions and conflicts between cultures show us that the overwhelming majority of these religious ideas must be partly or completely manufactured.

Given that people often try to explain the unknown with specious assumptions of a supernatural quality, it appears that having an answer to whatever question(s) religion solves is more important than whether or not the answer is correct. In other words, we are predisposed to religion more than we are to truth.

You can take away a man’s gods, but only to give him others in return.

— Carl Jung (1957)

These "religious answers" that have no evidential basis may provide the claimant with some evolutionary benefits. For example, an unprovable claim of divine protection, or even divine favor, may be enough to intimidate competitors or dissuade them from belligerence.

Yet, the credulity of one's competitors will not extend to each whimsical creation of the imagination. Gods are believed and acted upon in ways that fairies and monsters are not. Fear might explain this discrepancy: disobeying the gods could have eternal consequences, while disobeying the Fae might only require a bigger flyswatter. However, if fear of God is a reason to believe, why invent God in the first place?

Perhaps the answer is that people fear the falsity of belief more than the consequences of unbelief. Our minds have evolved in such a way that religious claims appear to be parasitic upon our natural desires and motivations. We may want religion to be true because the chance of eternity in hell is more appealing than the notion of existential oblivion and less farcical than the wish for unconditional paradise.

There is a great deal of experimental evidence to suggest that religion is a desirable and comforting belief system to adopt. In the next sections, five theoretical reasons for this evidence are discussed.

Reason 1: Fear of Death

A fundamental precept of evolutionary psychology is that all life on Earth is driven by the desires to survive and reproduce. In humans, our greater psychological complexity may come with more sophisticated ways of fulfilling these desires, such as a self-serving delusion about an afterlife and, by necessity, a god who oversees it.

Many world religions include the notion of an afterlife, whether through heaven, hell, an invisible spiritual plane, or reincarnation. Given that all life is disposed to search for ways to evade death, there may be no greater temptation than to replace our fear of death with a belief in eternal life. Convincing oneself of this reality may protect believers from crippling levels of existential anxiety, grief, guilt, and depression.

However, we fear death for obvious protective reasons and doing away with it might be problematic. Individual differences in proneness to (or coping with) anxiety may explain why some people are more willing and able to mitigate their fear of death with afterlife beliefs. Furthermore, strong or happy people have more to lose in death than vulnerable or depressed individuals, and the latter may therefore find it easier to do away with their fear of death.

Reason 2: Self-Righteousness

A second reason to believe in God is the moral code that comes along for the ride. It is beneficial to be perceived as a good person because of the increased opportunity for interpersonal alliances, mating opportunities, and reciprocal exchanges. Identifying with a religion and displaying its markers (e.g., wearing a cross, or praying publicly) means that these benefits can be enjoyed because onlookers are able to assume that you follow the religion's moral code.

This makes religion a shortcut to increased trust and cooperation. Of course, there are plenty of "false prophets" who pretend to be religious. Furthermore, individual advantages are lost if everyone conforms to the same moral code (although clergy still outperform nonclergy). Generally, however, increased trust and cooperation within a society benefits everyone within it.

Much like the first reason for believing in god, strong or happy individuals have less need for these benefits because they are either already content or their authority ensures the cooperation of their peers.

Reason 3: Answers to the Big Questions

A third reason is the philosophical and practical knowledge that religion purports to offer. It is undoubtedly satisfying to know what the purpose of humanity is, who created the universe, why bad things have happened to us, what happens when we die, and so on. These questions deal with existential concerns, such that our attention is drawn to answers that we may be highly motivated to believe. In other words, having answers may be more important than whether the answers are correct.

Again, however, some people will be more likely to believe than others. Uncertainty about these big questions feels unpleasant, and having answers alleviates those feelings. People with a great deal of uncertainty, anxiety, or existential concerns in their lives may be more likely to shortcut their thinking than others.

At least in our ancestral past, having these answers also promised power, prestige, and dominance to those in the know (or who claimed to know). However, as with the other reasons, individuals possessing a significant intellect or position of power may not need or value the importance of these assumed answers.

Reason 4: Ultimate Justice and Safety

The fourth reason why people believe in God is the notion of ultimate justice. For most people, concerns and worries are alleviated by friends and family. However, all Earthly alliances have their limits. Through theistic belief, people acquire a watchful, caring eye over all their doings, giving an unparalleled feeling of safety and security. Communication with gods, or prayer, is the reminder and emphasis of this fatherly relationship.

It follows that all those who transgress against God's law and harm his followers will not escape his surveillance and judgment. Ultimate justice of this kind is an extremely comforting idea, akin to karma. How many times have you wished a wrongdoer would receive his or her comeuppance? Religions typically guarantee it, but those who have been wronged less in their life will be less likely to see the appeal.

Jesus is God's supposed perfection embodied within man.

Reason 5: Easily Achieved Growth

The final reason is our desire to perfect ourselves. Nature gives us the capacity to grow mentally, physically, and socially through education, exercise, and friendship. However, religion offers a much more accessible journey to perfection via the adoption of its principles.

For example, acceptance of religious morality and knowledge convinces believers that they have progressed significantly toward the perfection embodied in the gods. However, most religions go much further, describing those who convert as "chosen" by gods to be in their company after death.

Christianity and a few other religions have taken the idea of growth to a new level. These religions utilize demigods in which a perfect god is embodied within a human being (e.g., Jesus), which provides followers with a sign-posted route to perfection through the imitation of the god’s actions as a man.

In other religions, the icon for imitation might be a divine prophet (e.g., Muhammad). Religions that have withstood the rigors of cultural selection often provide such blueprints for perfection (e.g., Buddha), and their popularity is a telling manifestation of their psychological appeal. Nevertheless, those who achieve growth easily through natural means will be less likely to follow the "apotheosis" path outlined by religion.

Individual differences can explain why some people are more likely to believe in God than others.

Who is Most Susceptible to Belief in God?

These five reasons explain how and why religions appeal to many facets of our naturally evolved minds. Religious belief can provide a sense of superiority, ultimate justice for wrongdoers, a path to moral and spiritual perfection, a provision of security and immortality, a wealth of strategic knowledge about mankind and the universe, and a special alliance with the most powerful and knowledgeable entity in the universe.

Religions take our naturally evolved desires and tempt us with a perfect, comforting, and easily achievable solution, requiring only that we sacrifice our natural ambitions and skepticism to make way for it. The irony is that many religions tell us to avoid temptation (e.g., Christianity): an instruction that should see them removed from existence.

The attentive reader may have noticed that each reason to believe in God came with a caveat: an example of the type of person who would not be tempted. A pattern emerged that has been touched on by Nietzsche and Freud: that religion is a sanctuary for the weak and vulnerable.

Strong, capable, and happy individuals have less need for the comforts of religion and so are less motivated to believe in them. Rather, religious belief is for those who have all but given up on achieving strength in their natural life. Faith provides them with an illusion of strength, and their minds perform the mental gymnastics required for that illusion to become their reality. Of course, such motivated reasoning must at least appear plausible to the believer, and so various potential costs are adopted (e.g., hell).

Nietzsche Explains Religion's Selective Appeal

For example, Christianity has always been prevalent in the subjugated working classes. It is taught in schools and prisons where weaker minds are encountered. It is offered in hospitals and help groups where desperate and traumatized people reside. It is exported to Africa and Asia where starving and vulnerable people are receptive to its claims. It is in these places where the greatest level of conversion occurs. Contrary to Biblical doctrine, it is the abandonment of hope, at least in Earthly pursuits, that brings one closer to God.

At least on the individual level, then, religion is antithetical to Darwinism and, through the conversion of others, a believer only seeks to weaken society to their level, dissolving the inequality that existed in their natural life. Conversion also strengthens the believer by validating their illusion and by providing a greater alliance of opinion.

Of course, what a believer fabricates in their mind is the exact opposite. They see conversion as a charitable act to help the weak achieve their perceived position of strength. This reversal of evolutionary law is what riled Nietzsche: the audacious belief that crippling fellow minds is a charitable act.

Satan supposedly tempted Jesus on the mountaintop, but God may be a far greater temptation than the Devil.

Summary

If a supposed truth gave no rational explanation for its truthfulness but was extremely tempting for a number of psychological reasons, would you not doubt your sanity for believing it to be true?

Unfortunately, religion is a temptation of such ambrosial intoxication that it precipitates the suspension of rational thought. Those who through distress or affliction are disposed to apply less scrutiny to comforting propositions will find religion too appealing to ignore.

Religious belief is nothing more than the substitution of our natural ambitions with an unlikely truth that fulfills our needs in a much easier manner. Once one has resigned to failure for natural methods, religion presents an easier means to achieve the objectives ingrained in us by evolution.

This is an extremely thought-provoking article which I enjoyed reading. I feel that the primary reason for the belief in God is because a man knows he will die and is afraid of the unknown. Many people like me also believe in a God because he is someone who will take care of and comfort people in times of need. Yes, religion is for the weak. I was brought up as a Catholic and have learned that the easiest times in one life to be a good Catholic is when one is young or very old.

Thanks for the clarification, Thomas, and for approving my comments.

Relax Joel, I just hadn't seen and approved your comment yet. I've gotten a few nasty personal comments in the past about things like my "character", so I set things to only appear once I get around to approving them.

Joel Lantz from Cincinnati, Ohio suburb on April 29, 2017:

Your summary deletion of my EVIDENCE-for-God comment yesterday — which exposes the falsity of your condescension — reveals something about your character. Though you’ll delete this comment as well, I suggest considering whether suppression of truth is ultimately in your best interest. Is that REALLY how you want to live?

Joel Lantz from Cincinnati, Ohio suburb on April 28, 2017:

This condescending article neglects the reason that most convinces me, a PhD physical scientist: EVIDENCE. Evidence including but not limited to:

..... Medically attested, non-medically achieved healings of irreversibly-damaged body parts that simply cannot have a natural explanation (e.g. orders of magnitude faster than natural tissue growth).

..... Account after account of dramatic and positive life transformations in response to humble submission to the gospel message (including that of an ISIS guy who admitted to having enjoyed murdering Christians).

..... Scientific correlates that substantially support the existence of God. Though such correlates do not prove the existence of God, even science only variably *supports*, not proves, its positions — varying from ‘laws’ (nearly proven) to little more than educated conjecture.

It’s impossible to adequately illustrate this point within the 8192-character limit of a comment. However, readers willing to entertain the existence of evidence for God can read my HubPages article on evidence and/or ‘Bridges for honest skeptics’ — my freely-downloadable (and quickly locatable) e-book.

Kylyssa Shay from Overlooking a meadow near Grand Rapids, Michigan, USA on April 02, 2016:

I think the differences between people more susceptible to belief and those less susceptible have less to do with how well beliefs soothe their hopes and fears and more to do with how their minds process evidence and index memories.

I've noticed that believers can do something I can't; they can genuinely hold two or more beliefs that should be mutually exclusive. For instance, they could believe that a fertilized zygote is a thinking and feeling being and that the brain is where our thinking and feeling happens without seeing any conflict between those beliefs. I've often wondered if it's not some kind of indexing issue that causes them to be unable to see how the two beliefs are related.

People who are only capable of believing in things they think are real are also unlikely to be susceptible to belief in God unless they were indoctrinated early enough that they think God is real.

I've never seen any positive correlation between the desirability of a belief and the possibility of it being based on reality. I don't have any idea what mental or emotional gymnastics allow people to believe in things they find desirable rather than in things that reflect reality.

I'm not confident, assertive, or any of the other things you mention might be characteristics of non-believers.

Cheers Spongy! I hope I can compare to your book! Some day I hope to write in more depth on this subject. I appreciate the share too!

Thomas Swan (author) from New Zealand on April 03, 2013:

Thank you Paul, I agree that existential anxiety is the main motivator for religious belief. Most academics fail to realize that ancient religions were almost solely concerned with death rituals and preparing for the afterlife. They concentrate on modern rituals, which is fine, but then make sweeping generalizations about religion in general. Thanks again for the kind comment and share!

Jake Ed from Canada on April 02, 2013:

Very interesting. I was actually just about to crack a book on this subject. Thanks for getting me warmed up for it. Sharing!!

Paul Richard Kuehn from Udorn City, Thailand on April 02, 2013:

Thomas,

This is an awesome hub and you make some very good arguments. I think people believe in God because they know they are going to die and are afraid of the unknown. By being comforted believing that there is a God who will take care of their souls, people can accept death more easily. Voted up as awesome and sharing with followers.
