Free will announced its own irrelevance to me at around midnight on a Tuesday, in front of an open refrigerator, over the question of whether to eat the leftover daal or nothing at all. By then I had already decided what to wear for the next morning, which route to take to dodge the broken construction on University Road, which of four unanswered work messages to reply to first, and whether my mother’s comment about my cousin’s wedding needed a real answer or the practiced non-answer I keep in reserve for family matters. 

By the time I reached the fridge, something in me had simply stopped offering opinions. I stood there for a long moment, not choosing and not quite refusing to choose, waiting for some inner committee to reconvene. Eventually I closed the fridge and went to bed hungry. It felt easier. 

That flicker of nothing, not real indecision, more like the temporary absence of a self willing to decide, is where this piece actually starts. It is the closest most of us get, on an average day, to the oldest argument in philosophy. We do not sit around debating determinism at the dinner table. We just notice, some nights, that the person who is supposed to be choosing seems to have clocked out early, and that whatever happens next will be decided by habit or by whichever option needs the least extra thought. I have started to wonder whether that nightly tiredness is not just a failure of willpower, but a small, honest glimpse of something philosophers have argued about since long before anyone had a refrigerator to stand in front of. The feeling of choosing might be a story we tell after the fact, rather than a power we actually use in the moment.

I want to be careful here; because it would be easy to dress up ordinary tiredness in fancy language and seldom call prophecy. Being exhausted after a long day does not, by itself, disprove free will. But the specific shape of that exhaustion, the way the hundredth decision of the day feels nothing like the first, points at something real. 

In the morning I can weigh my options carefully. By midnight, my brain goes on autopilot. I take the easier path, order the same food I always order; a beef cheese burger with pizza fries as an appetizer and a 500 ml pepsi. Ignore plans that I made with friends because I just couldn’t care less. 

If free will is a muscle I use all day, it is a muscle that tires in a very particular, very repeatable way. And a will that gets tired on a schedule already behaves less like some grand, sovereign power inside us, and more like an ordinary biological process. This isn’t just my own observation though. It has a name in psychology, decision fatigue, and a research history that is more contested, and more interesting, than the popular version usually lets on. 

In the late 1990s, the social psychologist Roy Baumeister and his colleagues proposed that self-control draws on a single, limited resource, much like a muscle that tires with use, an idea that came to be called ego depletion. The theory was simple and intuitive, and for close to two decades it shaped how psychologists, and later a great many self-help writers, talked about willpower: as a tank that empties over the day and needs refilling.

The trouble is that when other laboratories tried to reproduce the original ego depletion effect on a larger scale, it mostly failed to show up. A large, carefully pre-planned study involving more than two thousand participants across over twenty laboratories found no reliable evidence for the effect, and a second, similarly rigorous multi-lab study a few years later reached much the same disappointing conclusion. 

Baumeister has continued to defend the underlying idea, arguing that the replication studies used a weaker version of the tiring task than his original experiments, a real and still unsettled disagreement over method. What survives the controversy, interestingly, is not the specific mechanism Baumeister first proposed, but a smaller and more modest claim. Decision quality does tend to get worse as the number of decisions pile up, whatever the exact cause, and people who believe willpower is a limited resource behave as if it is, even when the biological story behind that belief turns out to be shakier than advertised.

A related and often quoted example is the 2011 study of Israeli parole judges, which found that prisoners were far more likely to be granted parole in the sessions right after a food break than in the sessions right before one. Favourable rulings reportedly fell from roughly two thirds of cases to almost zero as each session wore on, then jumped back up after the judges ate. The finding was widely reported as proof that even trained legal professionals give in to decision fatigue. But this study has also been seriously questioned. Other researchers who looked at the same records argued that the pattern had less to do with mental exhaustion and more to do with how cases were scheduled. Prisoners without a lawyer, who are statistically less likely to be granted parole anyway, tended to be grouped near the end of each session, right before a break, for entirely administrative reasons that had nothing to do with the judges’ state of mind. 

I mention this not to dismiss the original finding, but because the argument around it is, in miniature, the whole free will debate. A pattern that looks like proof of some hidden mechanical limit on human choice turns out, on closer inspection, to allow more than one honest explanation. The honest position is to sit with that uncertainty rather than resolve it too quickly in either direction.

If decision fatigue only tells us that will has a battery life, neuroscience raises a stranger and more unsettling possibility, that even a fully charged will might be reporting on a decision it did not actually make. In the early 1980s, the neuroscientist Benjamin Libet ran an experiment that has haunted the philosophy of mind ever since. He asked volunteers to flex a finger or wrist whenever they felt the spontaneous urge to do so, while watching a fast-moving dot on a screen so they could later report the exact moment they became consciously aware of deciding to move. 

Meanwhile, electrodes on their scalps recorded a slow build-up of electrical activity in the brain’s motor regions, known as the readiness potential, which begins before any muscle actually moves.

What Libet found was startling. The readiness potential began, on average, several hundred milliseconds before participants said they became aware of their intention to move, roughly half a second of brain activity coming before roughly a fifth of a second of felt decision, both arriving before the muscle itself ever twitched. Read one way, this suggests the brain has already begun preparing an action before “you,” the conscious narrator, have any idea it is coming. Consciousness starts to look less like a decision maker and more like a press secretary, announcing choices that were made elsewhere, slightly earlier, without ever being consulted.

Libet himself was more careful than many of the people who later popularised his work. He suggested that while the start of an action might be unconscious, conscious will could still act as a kind of veto in the narrow window before the act happens, the power to stop a movement already in motion, even without the power to have started it. Other researchers have gone further and questioned the original interpretation altogether. A well known alternative account, developed by the neuroscientist Aaron Schurger and colleagues, argues that the readiness potential may not represent a decision being made at all. It may simply be the ordinary background noise of a brain that happens to cross a certain threshold at a moment that lines up with when a person, already primed to act “whenever,” decides to act. 

On this account, Libet’s experiment measured the timing of a kind of coin flip the brain was always going to make, not the hidden authorship of one specific choice. The debate remains open among specialists, and most philosophers who have looked closely at Libet’s method, including doubts about how reliably people can time a fleeting inner experience against a moving dot, have not treated it as a knockout argument against free will. What the experiment reliably shows is narrower and stranger than the popular version suggests. The link between brain activity and the felt experience of deciding is not as simple, or as neatly ordered in time, as it feels from the inside.

None of this is really new. It is old wine poured into an EEG shaped bottle. The philosophical argument over determinism goes back at least to the Stoics and has been fought, in different vocabularies, ever since. Hard determinists, of whom the neuroscientist and writer Sam Harris is a well known present day voice, argue that because every thought and choice arises from prior causes, our genes, our upbringing, our brain chemistry, the last conversation we had, the feeling of being a free author of our own actions is, however real it feels, an illusion. We would do better, on this view, to build our ethics and our compassion on that recognition instead of pretending it away. 

On the other side sit compatibilists, among them the philosopher Daniel Dennett, who argue that this whole framing sets up a contest between free will and causation that free will was never meant to win, because the free will worth caring about was never freedom from causation in the first place. It is the ability to act on your own reasons, weigh different options, and respond to argument and evidence, all of which remain perfectly real and perfectly worth valuing even inside a fully caused universe. A smaller group of thinkers, sometimes called metaphysical libertarians, still hold out for some kind of genuine randomness, at the level of quantum physics or otherwise, that leaves room for choices that are not simply the last link in a chain of causes stretching back to the Big Bang.

What strikes me, coming back to this argument as an adult rather than as a philosophy student cramming for an exam, is how little the actual research settles it either way. Even if Libet’s readiness potential turns out to mean exactly what the most dramatic reading claims, compatibilists have a ready answer. So what, they say, the brain is where decisions happen, and “you” are your brain, not some separate ghost waiting to be consulted before it acts. Even if decision fatigue turns out to be real in some smaller, better defined form than Baumeister’s original muscle idea, that only tells us something about the conditions under which careful thinking breaks down, not about whether that thinking was ever “free” in the deeper sense to begin with. The science keeps narrowing the space this argument can live in, without ever quite reaching its floor. That is less a failure of science than a hint about the kind of question this really is.

Here in Pakistan, this argument does not usually arrive dressed as neuroscience first. It arrives dressed as theology, and it arrived long before Libet’s EEG machine. Islamic scholarship has argued over the relationship between divine decree and human responsibility for well over a thousand years, and the shape of that argument will feel oddly familiar to anyone who has followed the Western debate on determinism. In the earliest centuries of Islamic thought, the Jabriyya took a position close to hard determinism, holding that God’s power and knowledge leave no real room for independent human choice, that we are, in effect, compelled in everything we do. 

Against them, the Qadariyya and later the rationalist Mu’tazila school insisted on real human free will, largely because divine justice would make no sense if people were punished or rewarded for actions they had no power to avoid. Between these two positions, the Ash’ari and Maturidi schools of thought that came to dominate mainstream Sunni theology worked out something close to a middle path, often explained through the idea of “acquisition,” or kasb. God creates the power and the act, but the human being genuinely acquires it and is answerable for it, a formula that, in its structure, is not so far from Dennett insisting that free will can be real and meaningful inside a fully caused universe, even if the cause named is a different one.

I grew up hearing “Allah ki marzi,” it is God’s will, offered as comfort after some disappointment, and I used to hear it as a kind of surrender, an excuse dressed up as piety. I am less sure of that now. 

Reading the actual theological arguments, rather than absorbing them secondhand through family conversation, what strikes me is that mainstream Islamic scholarship was never comfortable with pure fatalism, any more than it was comfortable with the idea that human beings write their own story from nothing, with no help or hindrance from anything beyond themselves. The Prophet is reported to have discouraged his companions from arguing too deeply over questions of divine decree, not because the question does not matter, but perhaps because it is a question better lived with than solved fully, an instinct that, I notice, modern philosophers of mind have reached from a completely different direction, several centuries and one scientific revolution later.

So here is the actual claim in the title, and I want to state it plainly rather than let it hide behind throat clearing. I no longer think free will is mainly a fact about the universe that we are still gathering evidence for. I think it is, first and foremost, a coping mechanism, a story the mind tells itself so that the sheer scale of causation, all those genes and childhoods and circumstances none of us chose, does not flatten us into paralysis. This is not the same as saying free will is a lie, because “coping mechanism” does not mean “falsehood.” 

A grief counsellor does not tell you the stages of grief are fake just because they are a psychological process rather than a physical law. A coping mechanism can be genuinely necessary and philosophically unresolved at the same time, and I think free will sits in exactly that uncomfortable, useful place.

Think about what believing in free will actually does for a person, day to day, whether or not it is philosophically airtight. It lets you feel proud of your successes without immediately having to trace them back to an accident of birth, timing, or luck, which would otherwise turn every achievement into an anticlimax. 

It lets you hold other people responsible for cruelty without first having to work out, case by case, how much of that cruelty came from a hard childhood or a chemical imbalance, a calculation no society has ever really been able to make with any precision, and one that, taken to its logical end, would dissolve the whole structure of blame, apology, and forgiveness that daily life depends on. And it lets you stand in front of a fridge at midnight, tired and undecided, and still believe that tomorrow, with more energy in the tank, the “real you” will show up and choose better. 

That is, if you think about it, a strange thing to believe, since the self doing tomorrow’s choosing is itself just another link in the same chain of causes as tonight’s exhausted non-decision. And yet I believe it anyway, every single night, because the alternative, treating myself as a passenger in my own life, simply watching decisions arrive rather than making them, is not a belief I can actually live inside for very long. Determinism might be true. It might even be more likely true than not, given the evidence. But it is one of the very few ideas I can understand with my mind while finding it almost impossible to live by, the way you can understand that the earth is moving through space at enormous speed without ever, for a single second, feeling yourself move.

Baumeister’s own work, in a roundabout way, offers something like support for this idea, though not the part that made him famous. The part of his research that survived the replication crisis intact, that people who believe willpower is unlimited perform better under pressure than people who believe it is a resource that runs out, is itself a small, neat demonstration that believing in your own agency changes outcomes, regardless of what turns out to be metaphysically true about that agency. If believing you have more control produces more control-like behaviour, then the belief is doing real work in the world, whatever its ultimate truth. That is exactly what a coping mechanism is meant to do. Not describe reality with perfect accuracy, but make reality livable, and in this case, even measurably easier to get through.

I never did settle the question of the daal. I went to sleep, woke up hungry, and made a very ordinary decision the next morning to eat breakfast, which felt exactly as free as any decision has ever felt to me. Which is to say, it felt completely free, and I have no way of proving from the inside that it actually was. That, I have come to think, is the honest ending to this whole argument, for an ordinary person living an ordinary life rather than adjudicating a seminar. The feeling of choosing and the deeper truth about choosing may simply run on separate tracks that never fully meet, and most of us are only built, day to day, to operate on the first one.

What I can say, after spending some weeks with Libet’s readiness potential, Baumeister’s contested muscle, Dennett’s patient reframing, and my grandmother’s quiet acceptance of qadar, is that the question is not embarrassing to still be stuck on. It has resisted a final answer from neuroscientists with electrodes, philosophers with four centuries of careful argument, and theologians with revelation on their side, which is not a small group to be confused alongside. 

Perhaps the more honest position, and the one I have landed on for now, is that free will does not need to be metaphysically real to be practically necessary, that it works less like a fact we discovered and more like a tool we picked up, a very long time ago, because the alternative was too hard to live with. I still do not know, in any strict sense, whether I chose to write this sentence, or whether it was always going to arrive, word by word, exactly like this. But I notice that not knowing has not stopped me from writing it, and that, more than any experiment, might be the closest thing to an answer any of us actually gets.
