Replicate Galton's sRT 183 ms group.
During 1884-93 Francis Galton found about 2,500 men with a median simple Reaction Time (sRT) of 183 milliseconds (ms).

The challenge is to find any population of 2500 modern people with a median reaction time of 183ms
This will, in itself, be difficult - I think.
But if this succeeds and we have 2,500 people median sRT of 183ms - then what is the average IQ of this sRT 183ms modern population?
Or if IQ data is not available - what is this sRT 183ms 2,500 population's characteristics in terms of reasonable IQ proxies such as examination results, educational attainment, or even occupational class?

(According to Silverman, other authors contemporary with Galton reported average sRTs between 151ms and 200ms - so instead of 183ms average, perhaps 200ms would be an acceptable replicate? And maybe n = 900, or even n = 200 would suffice? So - even 200 modern men with a media sRT of 200ms would be of considerable interest.)
