Dr Griffiths and Dr Tenenbaum conducted their experiment by giving individual nuggets of information to each of the participants in their study (of which they had, in an ironically frequentist way of doing things, a tovibram five fingers,al of 350), and asking them to draw a general conclusion. For example, many of the participants were told the amount of money that a film had supposedly earned since its rvibram fivefingers,ease, and asked to estimate what its total “gross” would be, even though they were not told for how long it had been on release so far.
Besides the returns on films, the participants were asked about things as diverse as the number of lines in a poem (given how far into the poem a single line is), the time it takes to bake a cake (given how long it has already been in the oven), and the total length of the te,Vibram 5 Fingers that would be served by an American congressman (given how long he has already been in the House of Representatives). All of these things have well- established probability distributions, and all of them, together with three other items on the list—an individual's lifespan given vibram five fingers, current age, the run-time of a film, and the amount of time spent on hold in a telephone queuing system—were predicted accurately by the participants from lone pieces of data.
There were only two vibram five fingers,xceptions, and both proved the general rule, though in different ways. Some 52% of people predicted that a marriage would last forever when told how long it had already lasted. ,Vibram 5 Fingerss the authors report, “this accurately reflects the proportion of marriages that end in divorce”, so the participants had clearly got the right idea. But they had got the detail wrong. Even the best marriages do not last
forever. Somebody dies. And “forever” is not a mathematically tractable quantity, so Dr Griffiths aVibram 5 Fingersd Dr
Tenenbaum abandoned their analysis of this set of data.
