Quiz: which of these 16 personalities best describes how rational you really are?

Detective? Free spirit? Explorer? Which of these personality types best describes how rationality affects the decisions you make? A new test hopes to answer this for you.

Spencer Greenberg, a mathematician by background and a founder of a quantitative investment firm, is the person behind US-based clearerthinking.org, a not-for-profit project he created in 2012 to help people make the right decisions.

"There are many things people can learn from cognitive science and maths to improve their decision-making," he told i100.co.uk, "but these rarely trickle down to a popular level."

Mr Greenberg said he had never received an accurate result from the rationality tests as he unfortunately knew all the answers already.
