Towards the bottom of the page they said they've only guessed age correctly 51% of the time, which lines up with there being no correlation between age and ability to generate random sequences
> Tap a sequence of 10 dice rolls. Make it look as random as possible; another person should not be able to tell if you made it up or if it was from real dice rolls.
And this is the excerpt from the study they mention
> Click on a number between one and six as randomly as possible to produce the kind of sequence you'd get if you really rolled a die [...]
I made the same mistake as thombles, the new instructions make it sound like the objective is to trick a human. The original clearly states the objective is to be random.
They are not the same objective, as humans are terrible at recognizing randomness.
> so that if another person is shown your sequence of digits from 1 to 6, he/she should not be able to tell whether these numbers were produced by a real die or just “made up” by somebody.
I have a really hard time rationalizing why you would leave that part out of your quote and drew the conclusion you did. The original task was clearly also about creating patterns that a human would recognize as random.
The fundamental issue with a randomness metric for sequences is that an idealized independent generator will under-perform vs a constrained generator that excludes low scoring sequences.
