An exercise in a course I developed consists in asking candidates who consider themselves sceptical to create a voodoo doll and add to it a picture representing the face of a loved one. They must perforate the doll using a needle. The majority of them refuse to take the test or manifest psychological frictions despite their awareness about the irrationality involved. An appropriate inquiry regarding scepticism is: what does it mean to be ‘sceptical thinkers’? Are we really sceptical thinkers? Evolutionary biologist Richard Dawkins coined the definition ‘memes’: a meme is an information that is copied from person/culture to person with variations but without a critical analysis and evaluation of it. Memetic thinking cares only about replicating itself while it does not examine the sound-validity or unsound-invalidity contained in memes.
