You're actually reducing detail.  But since the number of
pixels that is used to express a slightly fuzzy line for
example, is reduced it may often /seem/ as if the "apparent"
sharpness was increased.  But all you've really done is
reduce the amount of information used to express (represent)
the fuzz [as well as the line itself].
