From a Guardian opinion piece: Believing that life is fair might make you a terrible person
You needn’t be explicitly racist or sexist to hold such views, nor committed to a highly individualistic political position (such as libertarianism); the researchers controlled for those. You need only cling to a conviction that the world is basically fair. That might be a pretty naive position, of course – but it’s hard to argue that it’s a hateful one. Similar associations have been found between belief in a just world and a preference for authoritarian political leaders. To shield ourselves psychologically from the terrifying thought that the world is full of innocent people suffering, we endorse politicians and policies more likely to make that suffering worse
It’s very easy to fall into traps of this type, living in our little bubbles of relative harmony. I do it and have to fight my personal biases on a regular basis.
The conclusion says it all:
if there’s no good explanation for why any specific person is suffering, it’s far harder to escape the frightening conclusion that it could easily be you next.
