When we are shown two options, our eyes tend to flick from one to the other and back again several times as we deliberate on the pros and cons of each.
Researchers at Johns Hopkins University in the US have found that the speed with which our eyes dart between options gives away our true preference and predicts the ultimate decision we will make.
This quick eye movement – called a saccade – is what allows you to read; your focus travels abruptly from word to word, fixating briefly on some words before moving on to construct meaning from a block of text.
