Our brains have a lot of ways of tricking us. In many ways, they are worse enemies to our faculties of logic and critical thinking than even some exterior forces, for the ‘tricks of the mind’ often facilitate demogogues, cult leaders, and even magicians with their illusory machinations.
New research led by cognitive scientist Claire Sergent has found that conscious experience can be altered retrospectively. Specifically, the information of visual input can be ‘altered’ by the brain a split second later by distracting our attention elsewhere.

The research involved asking people to stare at a centre point of a screen with two empty circles either side.
At some point, one of the two circles would fill with randomly oriented stripes for just 50ms (one twentieth of a second) and afterwards the participants were asked to say which direction the stripes were pointing in.
