How To Reverse Someone’s Moral Compass

23 Sep

This article over at Scientific American People Can Be Tricked into Reversing Their Opinions on Morality is pretty interesting, I wonder if it could be applied to other things…

The researchers, led by Lars Hall, a cognitive scientist at Lund University in Sweden, recruited 160 volunteers to fill out a 2-page survey on the extent to which they agreed with 12 statements — either about moral principles relating to society in general or about the morality of current issues in the news, from prostitution to the Israeli–Palestinian conflict.

But the surveys also contained a ‘magic trick’. Each contained two sets of statements, one lightly glued on top of the other. Each survey was given on a clipboard, on the back of which the researchers had added a patch of glue. When participants turned the first page over to complete the second, the top set of statements would stick to the glue, exposing the hidden set but leaving the responses unchanged.

Two statements in every hidden set had been reworded to mean the opposite of the original statements. For example, if the top statement read, “Large-scale governmental surveillance of e-mail and Internet traffic ought to be forbidden as a means to combat international crime and terrorism,” the word ‘forbidden’ was replaced with ‘permitted’ in the hidden statement.

Participants were then asked to read aloud three of the statements, including the two that had been altered, and discuss their responses.

About half of the participants did not detect the changes, and 69% accepted at least one of the altered statements.

People were even willing to argue in favor of the reversed statements: A full 53% of participants argued unequivocally for the opposite of their original attitude in at least one of the manipulated statements, the authors write. Hall and his colleagues have previously reported this effect, called ‘choice blindness’, in other areas, including taste and smell and aesthetic choice.

I wish I could see what the actual questions were.
