of random sequence generation in the sense that there is no other way to predict the next digit, other than computing it (see kolmogorov complexity).

A relatively useless pseudo-random sequence with a period of seven bits is the result, but the point of this circuit is to educate rather than its utility. You can see it in operation in the video ...

They asked more than 3400 people between the ages of 4 and 91 to complete an online assessment that included five tasks designed to measure their ability to generate random sequences.

A uniformly distributed, random sequence is one where the points have an equal probability of landing anywhere on the interval. Take the sequence 0.142, 0.566, 0.274, 0.265, ...

That’s the aim of Bruno Sanguinetti and colleagues at the University of Geneva in Switzerland, who have created a quantum random-number generator (QRNG) that uses low-cost electronic components ...
