The History of Riddles

It might come off as a surprise to you, but riddles are pretty much ancient! And by ancient, we mean that the first riddles, in the very same format that we know and use today, appeared as far back as in Babylonian times. Mind you, the city of Babylon has existed since the 18th century BC — thousands of years before our days!

The first attempt to define what a riddle is in a scholarly way was made much, much later than that, though, around the end of the 19th century by Robert Petsch. His work was succeeded by Archer Taylor, who, in 1918-20, did a massive job of cataloging myriads of riddles. 

One interesting thing he has discovered is that some riddles are almost the same across continents and languages. Take, for instance, the writing riddle about black letters on white paper, the year riddle mentioning something in the count of twelve, and the cow riddle. Because, well, cows. 

Ultimately, all ancient riddles were based on the things that people saw every day and found of significant meaning. Because where else would you find a greater meaning than in the human experience and condition?

Why Do People Do Riddles? 

Intellectual Challenge

Solving riddles isn't just a leisurely pastime; it's a mental workout that challenges our brains and offers insights into our cognitive performance. This fulfilling activity caters to our dual instincts—one, the desire to showcase our intellectual competence, and two, the primal urge to conquer challenges. 

Cognitive Exercise

Essentially, brainteasers act as a platform to display our analytical thinking, problem-solving skills, and mental agility. As we unravel their complexities, we decipher their elements and relish the satisfaction of assembling the pieces into a coherent whole.

Aha! Moments

Moreover, riddles tap into our competitive spirit, triggering a determination to succeed. They’re not just riddles to solve; they’re quests to master. The sense of accomplishment that accompanies the final piece falling into place symbolizes our persistence and strategic acumen. In essence, puzzles become a stage upon which we demonstrate both our cognitive finesse and our yearning for victory, encapsulating the concept of being smart in action.

Higher IQ

Besides all this fun action and hefty rewards that solving really hard riddles gives us, solving brain teasers for around twenty minutes daily can raise your IQ! This isn’t just anecdotal; it was proved by rock-solid research by Michigan University back in 2011.
