I don’t believe that’s exactly correct either.
Since 100 is in the center of the bell curve, by definition, it will be the most common score.
Therefore 100 or less will be something more than exactly 50%, just as 100 and above will be. May 51% or 53%.
But I really do think this is nitpicking.
Recently read an article about how in the next decade probably millions of jobs as drivers (bus, truck, cab, etc.) will permanently disappear. The article was upbeat, pointing out that the displaced drivers could get jobs creating apps for Iphone and Ipad.
Studiously ignoring the rather glaring fact that someone with an IQ of 80 or 90 can function quite well as a driver, but is probably quite incapable of the creativity necessary to write apps.
Those jobs are secure for decades too come. Our nation is no where close to developing any type of system to replace them. Having the technology does not mean something is economically practical. Rails as far as local mass transportation are only functional in larger cities or heavilly populated areas and then are very limited at that. Trucks? LOL I see no rail tracks going down each road. Everthing we buy ships on a truck. Trucking is the quickest way short of airlift to move products point to point at desired destination even transporting coast to coast. The technology and the upfront R&D cost of a driverless nation will be cost prohibitive for decades to come.
Back in my early childhood {late 1950's-1960's} the "thinkers" believed that by the turn of the century {the year 2000} personal air travel vehicles or personal vessels would be the way people got to wherever they wanted to go.
The writer of that article obviously lives in Libbyland where common sense is the pennies a person uses to pay sales tax LOL.
BTW what did the Philosophy Doctorate Graduate say to his professor four years after graduation?
"Would you like Fries and a large drink with that"?
