The "1 in 5" example is the most prominent one (introduced at the start of the article), but I was more impressed with another one - "Do you say the word hello or charisma more". Similar is this. Try remembering two of your acquaintances (friends) and tell with whom you talked more last year. In many cases you would give the exact answer, but it comes not from the explicit knowledge somewhere in the "symbolic storage", it would be probably derived implicitly from two (or more) "neuron clouds" related to these two individuals. Just to leave the symbolic world whatsoever, let them be unnamed persons like a cashier in the shop. You still can derive this information. For me it's a special thing about the frequency and probably some other kind of properties/data. Being discrete/symbolic for the human tasks, they can come from a non-symbolic memory storage
