Both drive us to take risk. Wingsuit flying or roller coaster riding are motivated by our expectation of reward – a thrill – but wingsuit flying may also driven by an urge to avoid loss (in this case death). The likelihood of a thrill from base jumping or a roller coaster is close to 100%. But while the likelihood of death from a rollercoaster ride is close to 0%, the chances of dying from basejumping are considerably higher. The closer to the extremes, 0% or 100%, the more certain, whereas the closer to 50%, the more uncertain.
