A king wants his daughter to marry the smartest of 3 extremely intelligent young princes, and so the king's wise men devised an intelligence test. The princes are gathered into a room and seated, facing one another, and are shown 2 black hats and 3 white hats. The king tells them that the first prince to deduce the color of his hat without removing it or looking at it will marry his daughter. You are one of the princes. Note: You know that your competitors are very intelligent and want nothing more than to marry the princess. Show Hint Show Solution Hint: Based on what you know, why are the other princes unable to solve this puzzle? Solution: White. The king would not select two white hats and one black hat. Therefore the only fair test is for all three princes to be wearing white hats. 2. 100 Gold Coins

Sadly, others have ended up backfiring horribly — ruining lives and shaming the profession. Here are ten psychological experiments that spiraled out of control. 10.

Are you an ‘educated’ predator? The mad clambering for grades is detrimental to the process of acquiring education. Education – slick, elite, expensive education – for which, I attend classes, take exams and tap a phenomenal fraction of my parent’s hard-earned money. Education – there is no word so grotesquely misunderstood. No idea so ill-expressed. Little does anyone realise that the mad rat-race to score better grades does not ‘educate.’ On the contrary, the cut-throat dynamics of the relative grading system merely give us a taste of the usual rat-racing, throat-cutting, leg-pulling and back-stabbing competition that the corporate culture is characteristic of. Relative grading gives you the grade, but it ingrains in you the idea that your success is tied to another student’s failure. Better grade equals better education? Better grades are universally thought to be reflective of a ‘better educated’ student. Education, however, is not the skill of passing exams or surviving the scars of the corporate world.
