It is very hard to predict who is a liar. Professor Robert Feldman tells Eve Ash there is no particular profile or personality traits, nor can we necessarily tell from non-verbal behaviors if a person is lying. Nervousness can be confused with being deceptive. Besides we don't always want to assume someone might be lying (truth bias). People sometime devise narratives to fill gaps in their memory. Our lives are actually filled with lies of many kinds.
