The Weighted Sum
Captions available
The idea
A weighted sum multiplies each number in a row by a matching weight and adds — one score expressing a point of view about what matters.
In practice
Score melons by sound plus three times yellow: the weights are importance knobs, and these knobs favor yellowness.
Where people slip
No scorer is the truth — each is an opinion made exact; learning is the search for a good one.
