At almost every major sports event there will be commentators giving their opinions on the predicted winners, losers, or favorites. People tend to give commentators due credibility for their knowledge of the game and sometimes experience. For the layperson however it may be better not to give the event much thought. This is true when making predictions on your own. In a recent study, Dijksterhuis and colleagues (2009) asked participants to make predictions about random football matches two weeks prior to the event. Three groups were used in this investigation. Those who were asked to guess performed the worse. Those who were asked to think about their answers performed better. But the group that performed the best was the group who thought unconsciously.
One exception however is that making predictions unconsciously without prior knowledge is not recommended. The participants who performed the best in the investigation also perceived themselves as relatively knowledgeable. Those who made conscious decisions with relative knowledge are said to not give proper value to relevant information, hence why they performed worse. People who are essentially asked to guess tend to do worse overall. So next time there’s a football, or sports match for that matter, it might be better to not give it much thought about whom will win.
