Choice blindness: Do you know yourself as well as you think?

Here is an excerpt:

Clearly we lack self-knowledge about our motives and choices. But so what? What are the implications of this research?

Well, perhaps one general point is that we should learn to be more tolerant of people who change their minds. We tend to have very sensitive antennae for inconsistency - be this inconsistency in a partner, who's changed their mind on whether they fancy an Italian or an Indian meal, or a politician who's backed one policy in the past and now supports an opposing position. But as we often don't have a clear insight into why we choose what we choose, we should surely be given some latitude to switch our choices.

There may also be more specific implications for how we navigate through our current era - a period in which there is growing cultural and political polarisation. It would be natural to believe that those who support a left-wing or right-wing party do so because they're committed to that party's ideology: they believe in free markets or, the opposite, in a larger role for the state. But Petter Johansson's work suggests that our deeper commitment is not to particular policies, since, using his switching technique, we can be persuaded to endorse all sorts of policies. Rather, "we support a label or a team".

That is to say, we're liable to overestimate the extent to which a Trump supporter - or a Biden supporter - backs his or her candidate because of the policies the politician promotes. Instead, someone will be Team Trump, or Team Biden. A striking example of this was in the last US election. Republicans have traditionally been pro-free trade - but when Trump began to advocate protectionist policies, most Republicans carried on backing him, without even seeming to notice the shift.

The Selective Laziness of Reasoning

Abstract

Reasoning research suggests that people use more stringent criteria when they evaluate others' arguments than when they produce arguments themselves. To demonstrate this “selective laziness,” we used a choice blindness manipulation. In two experiments, participants had to produce a series of arguments in response to reasoning problems, and they were then asked to evaluate other people's arguments about the same problems. Unknown to the participants, in one of the trials, they were presented with their own argument as if it was someone else's. Among those participants who accepted the manipulation and thus thought they were evaluating someone else's argument, more than half (56% and 58%) rejected the arguments that were in fact their own. Moreover, participants were more likely to reject their own arguments for invalid than for valid answers. This demonstrates that people are more critical of other people's arguments than of their own, without being overly critical: They are better able to tell valid from invalid arguments when the arguments are someone else's rather than their own.

Lifting the Veil of Morality: Choice Blindness and Attitude Reversals on a Self-Transforming Survey

Hall, L., Johansson, P., and Strandberg, T.

Abstract

Every day, thousands of polls, surveys, and rating scales are employed to elicit the attitudes of humankind. Given the ubiquitous use of these instruments, it seems we ought to have firm answers to what is measured by them, but unfortunately we do not. To help remedy this situation, we present a novel approach to investigate the nature of attitudes. We created a self-transforming paper survey of moral opinions, covering both foundational principles, and current dilemmas hotly debated in the media. This survey used a magic trick to expose participants to a reversal of their previously stated attitudes, allowing us to record whether they were prepared to endorse and argue for the opposite view of what they had stated only moments ago. The result showed that the majority of the reversals remained undetected, and a full 69% of the participants failed to detect at least one of two changes. In addition, participants often constructed coherent and unequivocal arguments supporting the opposite of their original position. These results suggest a dramatic potential for flexibility in our moral attitudes, and indicates a clear role for self-attribution and post-hoc rationalization in attitude formation and change.
