Do you think that heads or tails is a game of pure chance? Think once more. A recent study suggests that calling the visible side of the coin before the flip will increase your chances of winning.

Researchers performed 350,757 coin flips and found that the initial side of the coin, the one that is up before the flip, has a slight tendency to land on the same side. Frantisek Bartos, from the University of Amsterdam in the Netherlands, said this technique will give you a 50.8% chance of winning. This work draws inspiration from a 2007 study led by Stanford University mathematician Persi Diaconis. Diaconis had proposed that a slight imbalance is introduced when a coin is tossed with the thumb, due to “pitch” and a slight inclination (In celestial mechanics, inclination is an orbital element of a bodies in orbit…). Frantisek Bartos confirmed this theory (The word theory comes from the Greek word theorein, which means “to contemplate, observe,…). According to researchers, the coin lands on the original side 51% of the time (Time is a concept developed by humans to understand…).
The effect is not uniform for everyone. Some pitchers have a much higher success rate than the 50.8% observed on average. Furthermore, this phenomenon does not occur if one chooses at random (In ordinary language, the word chance is used to express an efficient lack, otherwise…) heads or tails before each throw. And it doesn’t depend on the coin: none of the 46 different currencies tested showed any signs of bias.
To eliminate any advantage, simply ensure that the person calling “heads” or “tails” does not see the original side of the coin before the toss. Frantisek Bartos points out that this discovery might have implications in various fields, including gambling and sports.
