Question

Most people will accurately identify lying what percentage of the time?

Answer 1

The answer to this depends on what sources you are using, but some sources state that people identify lies only 55% of the time!

That's very little, considering that 50% is the chance level - this number would be the one used if we could never really use our intuition to guess correctly. For example if we guessed that every second person randomly lies that would give us the "chance level" of 50 %. (if exactly half of the people lied).

And in real life, we can tell 55% of the time if people are lying - this means we are slightly better than chance. 

We can conclude from this that we should never trust our intuition about whether people lie or not!
