We presume that we could have foreseen what we know happened. Finding out something has happened makes it seem inevitable.

Description: The Case Study: Among the oldest research methods is the case study (an observation technique in which one person is studied in depth in the hope of revealing universal principles.). Most of our early knowledge about the brain came from case studies of individuals who suffered a particular impairment after damage to a certain brain region.
