In the previous post, a link was created to provide some information on the cognitive bias- how are thoughts tend to be irrational and not based upon cost/benefit analysis as some cognitive models hypothesise. How rational are humans? To what extent do we choose our destiny or more importantly to what extent can our behaviour be influenced by unconscious ‘nudges’, that makes it seem like we chose something when in fact we didn’t – how do you even measure such an effect? Showmen like Derren Brown use this grey area to provide simple but high impact effects such as priming.
The following BBC documentary shows how the science of decision-making shows us free will is something more scarce than most of us think.
