Irrational, Biased or Predictable? How Do We Make Decisions? - Professor Ben Newell

What is this research about?

How many decisions have you made today? Do you like to be risky or play it safe? Do you always want things now or do you sometimes wait for (possibly) better things later? What makes a decision ‘good’, ‘bad’, ‘easy’ or ‘difficult’? Should we deliberate or ‘go with our gut’ and let our unconscious decide for us?

In this work explore a range of factors that affect our decision making and develop psychological and computational accounts of how and why we do the things we do.
