"a 2007 study by the National Endowment for the Arts5 concluded that Americans are not just reading less than they used to, but they are also reading less well."
Perhaps the first citation was supposed to be "writing less"?--Jeremy Mack

As someone suggest the formula in the book is not good BTW the exact formula it should be:
MT= a + b * log2(D/W + 1)
Where MT is the movement time it takes to move between two spots, which is what we’re trying to figure out. Variables a and b are the intercept and slope, respectively, which are usually determined experimentally. D is the distance between the origin and the target. W is the width of the target.--Fabrizio Di Carlo

"The formula for the ID is logarithmic" cannot be the cause of the statement that follows, because log only amplifies its argument if it is <1; the +1 removes that possibility.
Rather, size changes are amplified because size is a divisor. So if it is 0.5, changing it to 0.4 is just as effective as changing it from 500 to 400, and ID approaches infinity as size approaches 0.--Stephen Compall
