Someone I know is a pretty good guesser. One day we had a guessing contest, and went around the house guessing how many objects were in different containers.

I was surprised that I was outperformed every single time, and the other person guessed faster than I did every time as well. For example the person I was competing against guessed correctly, after taking less than five seconds to think, that a container had 218 marbles in it. This individual continued to perform consistently, test after test.

The person's accuracy rate over $10$ different tests was about $95$ percent, and $98$ percent for objects with over $200$ objects and less than $300$ objects.

What is the psychology of a person being able to accurately guess the number of objects in a container? Are there any neuro-correlates for this ability? Is there a certain time frame that one should guess in and not overthink too much?

I googled "the psychology of guessing objects" and didn't find anything useful. But I did find that as the number of objects increases, the accuracy tends to decrease linearly.

My own thoughts on the matter are:

1) It might have been a lucky day for the guesser.

2) They guessed with relatively few objects in the containers. If we had guessed with 500 or 1000 objects I think he or she would have seen a linear decrease in accuracy.

  • $\begingroup$ I organized the guessing event and recorded the results, is that not research and investigation into the matter? I will try to add more information however. $\endgroup$ – geocalc33 Jun 9 '19 at 12:43
  • $\begingroup$ what I mean is that attempts to answer your specific question "what is the psychology of a person being able to..." should be made by you (book or article reading, Goigle searching...) and shown in the question. The link in my previous comment should help understand why we ask for this. $\endgroup$ – Chris Rogers Jun 9 '19 at 12:47
