    Fait accompli on bottle bans

    Fait accompli

    The very fact of something taking effect makes people more likely to accept it, new research indicates. Right after a ban on selling plastic water bottles took effect in San Francisco, residents reported more positive attitudes towards the ban than when they were asked right before it took effect. When interviewed right after a ban on smoking in certain areas took effect in Ontario, smokers reported having smoked less in those areas in the past — as compared with smokers who were asked right before the ban took effect. Likewise, Americans reported more support for President Trump right after his inauguration than immediately before.

    Analyzing data on residential property sales and exploiting the timing of the unexpected lifting of a moratorium on new strip clubs in Seattle, economists found “no statistical evidence that the presence of strip clubs was associated with any abnormal property price declines,” while “the evidence suggests some excess price appreciation for properties located 1,000 to 2,000 feet from clubs.”

    In a series of experiments, researchers at the University of Chicago showed people a brief video clip of someone performing a difficult action (e.g., yanking a tablecloth from under tableware, throwing darts, doing the moonwalk a la Michael Jackson, juggling bowling pins). After watching the video clip over and over many times, people become significantly more confident in their ability to perform the action than if they’d watched the video once or received non-visual instruction. They were also more confident than their own actual performance might justify. In other words, binge-watching led to overconfidence.

    By comparing the ideological positions of voters and candidates for the US House of Representatives, political scientists found that “the ideological positions of individual congressional candidates have only a modest effect on citizens’ voting decisions,” such that voters are really just considering party affiliation, not ideology. As a result, ideological moderation is worth only 1 or 2 percentage points for congressional candidates.

    In several experiments, participants had to choose between identical tasks with different payouts. Each task was also said to “expire” after either a short or long period of time — though, in both cases, the expiration deadline was always longer than the time participants were told they’d have to complete the task. In other words, the expiration deadline was specious. Nevertheless, a significant fraction of participants chose the task with the lower payout when it had a tight deadline, suggesting how easy it is to create an illusion of urgency. This was particularly true for participants who thought of themselves as busy.
