Better decisions are enabled. For most kinds of decision making – selection and
promotion, for instance – more information is almost always better than less.
Additional information generally facilitates more trustworthy decisions, whether
they involve language skills or any other kind of ability. This philosophy is
clearly evident, for example, in such consequential decision-making contexts as
US college admissions (College Board, 2002).
Moreover, added information also enables more flexible decision making. For
example, compensatory selection strategies that allow a test taker’s strengths in
one area to compensate for weaknesses in another can, by definition, be employed
only when multiple sources of information are available
