If this is the true sequence of events, [Bear blogs in Scientific American], how could we be deceived into believing that we had intentionally made our choice before the consequences of this action were observed? This explanation for how we think of our agency would seem to require supernatural backwards causation, with our experience of conscious will being both a product and an apparent cause of behavior.Why they suppose backward causation is supernatural when telos is built into the natural world is unexplained. After all, the perception of the milk dish causes the thirsty kitten to cross the room. But not to worry. No self-respecting labcoater can specify a problem without also claiming to have solved it; not if he wishes to be published. Hence, in a study just published in Psychological Science, Paul Bloom and Adam Bear
explore a radical—but non-magical—solution to this puzzle. Perhaps in the very moments that we experience a choice, our minds are rewriting history, fooling us into thinking that this choice—that was actually completed after its consequences were subconsciously perceived—was a choice that we had made all along.Evidently, rewriting history is non-magical.
The abstract of their study runs:
Do people know when, or whether, they have made a conscious choice? Here, we explore the possibility that choices can seem to occur before they are actually made. In two studies, participants were asked to quickly choose from a set of options before a randomly selected option was made salient. Even when they believed that they had made their decision prior to this event, participants were significantly more likely than chance to report choosing the salient option when this option was made salient soon after the perceived time of choice. Thus, without participants’ awareness, a seemingly later event influenced choices that were experienced as occurring at an earlier time. These findings suggest that, like certain low-level perceptual experiences, the experience of choice is susceptible to “postdictive” influence and that people may systematically overestimate the role that consciousness plays in their chosen behavior.
|A salient point. LOL!|
The experiment went as follows. WEIRD students were presented with five white circles at random locations on a computer monitor, one of which would soon turn red. They were asked to guess which of the five would turn red. The researchers claim the students would "choose" which circle would turn red. Since the guess was "in their head," it's hard to grasp how the researchers knew. But afterward, the student would indicate whether he had guessed right, wrong, or 'ran out of time' [i.e. the circle turned red before they guessed], presumably telling the truth. The metric was the frequency of a reported success out of all instances in which the student claimed enough time to guess.
"Unbeknownst to participants, the circle that lit up red on each trial of the experiment was selected completely randomly by our computer script." Unbeknownst? TOF would have supposed it so, but perhaps these were psych students. Actually, computers generate 'pseudo-random numbers', courtesy of an algorithm, so they were not 'completely random.' Accordingly, the psych dudes believed that the students could only possibly have guessed right 20% of the time, thus discounting precognition and the fact that runs of random numbers will ofttimes generate clusters above and below the nominal value.
When a circle turned red "especially quickly," students reported success above 30% of the time and Bloom and Bear fell into a fit of the vapors. Fortunately, reported success dropped to "near 20%" when the color change was delayed longer. IOW, when given enough time, subjects guessed correctly around the theoretical value, but when they were rushed they grew confused and guessed that they had guessed correctly more often than was likely [assuming no clusters in the runs].
...the people who showed our time-dependent illusion were often completely unaware of their above-chance performance when asked about it in debriefing after the experiment was over. Moreover, in a related experiment, we found that the bias to choose correctly was not driven by confusion or uncertainty about what was chosen: Even when participants were highly confident in their choice, they showed a tendency to “choose” correctly at an impossibly high rate.The hidden assumption here is that one cannot be confused when highly confident. After all, Bloom and Bear are no doubt highly confident about their interpretation of their results. They conclude that
"Taken together, these findings suggest that we may be systematically misled about how we make choices, even when we have strong intuitions to the contrary."
Of course, they admit that they saw this effect only when the time scale was very short. And 30% is significantly higher than 20% only if the sample sizes were adequate and there were no clusters in the pseudorandom sequence of circles. There is no mention of the sample size, but TOF notes that students could have achieved the perfect desideratum of 20% by not choosing at all, and simply guessing the same general location each time. Thus, scores closer to 20% may be more indicative of of a lack of free choice than the higher scores.
A more speculative possibility [they write] is that our minds are designed to distort our perception of choice and that this distortion is an important feature (not simply a bug) of our cognitive machinery. For example, if the experience of choice is a kind of causal inference, as Wegner and Wheatley suggest, then swapping the order of choice and action in conscious awareness may aid in the understanding that we are physical beings who can produce effects out in the world. More broadly, this illusion may be central to developing a belief in free will and, in turn, motivating punishment.This is apparently the key: motivating punishment. After all, if free will is an illusion, it would be unjust to punish someone for doing something wrong -- like engaging in politically incorrect speech or publishing papers in social 'science'. The authors worry that the mentally ill might suffer the illusion of choice even at longer delay times. The understanding that we are physical beings who can produce effects out in the world is probably indicated more directly by eating an apple than by subtle inversions in guessing games. In any case, more funding is needed:
It remains to be seen just how much the postdictive illusion of choice that we observe in our experiments connects to these weightier aspects of daily life and mental illness. The illusion may only apply to a small set of our choices that are made quickly and without too much thought. Or it may be pervasive and ubiquitous—governing all aspects of our behavior, from our most minute to our most important decisions. Most likely, the truth lies somewhere in between these extremes. Whatever the case may be, our studies add to a growing body of work suggesting that even our most seemingly ironclad beliefs about our own agency and conscious experience can be dead wrong.Quick! Break out the smelling salts! Bear [and likely Bloom] is having an attack of the vapors and is already reifying his theory about the data as if it were itself a fact. Even their most ironclad beliefs about their own experiment can be dead wrong.
|The will is free to the extent that the intellect is uncertain.|
James Chastek discusses this experiment also and shows how it can be interpreted differently:
IOW, understood in the classical way, the experiment supports the doctrine of original sin, identifying subconscious pride as the origin, one inherited from our remotest ancestors.
- The object of freedom is truth. This is the true heart of the experiment. The disconnection between word and reality or thought and reality is exactly the evidence that proves one is not free. The experiment would have been far more appropriately done by a group of evangelical scientists trying to manifest the truth of Jn. 8:32, and I say “manifest” because the experiment assumes that the truth makes one free, and then finds a conclusion in keeping with this.
- There is a flattering lie in the heart that enslaves us. Since freedom is impossible apart from truth and we find some subconscious tendency away from truth, our subconscious is to some extent enslaved. Most of us are willing to admit to the more minor manifestations of this corruption of the heart: telling fish stories, leaving off unflattering details, making close calls in favor of ourselves, etc (and this is most likely the sort of behavior that the experiment was observing). But this corruption of the heart is often far from innocent: I’ll clean up my act tomorrow, I deserve a little fun, I’ve had a hard day and can’t live without it, I’m just doing my job/ following the rules, If you wanna make an omelet…
- The lie is a sort of self-assertion. The experiment is really saying “we have a subconscious bias toward our own competence and ability, even to the extent of rejecting truth”. Exactly. But there is already a vast literature in place that has explored and named this domain. The general name for self-assertion-unto-the-rejection-of-truth was sin, when sin enters into consciousness it becomes culpable, and when the culpable becomes habitual it becomes vice. These illusions of vice congeal and support each other in collective ways to form what Augustine called a city that was based on the assertion of self to the rejection of truth.
