The decision matrix

A score tells you where something landed. A matrix tells you what moved it.

Every number on this page is already somewhere else in the application — these are the weights the Edit applied to your profile, unchanged, with the row totals still adding up to the scores it showed you. What is new is the shape. Laid side by side, most criteria turn out to move every candidate together, which changes the numbers and decides nothing. Usually one or two are doing all the separating, and it is worth knowing which.

Every product type, ranked against each other.

Two is a duel. Eight is a table you will read once.

Each row is a candidate product type, each column a scoring criterion. A bar drawn right of a column's midline is a weight in that candidate's favour; a bar drawn left is a weight against.

What actually decided this

  • Performance sport tint and Pressed powder compact are 1 point apart. At that distance the ranking is a coin toss with extra steps — pick on the job you actually need done, not on the order.
  • The column doing the separating is coverage match — 5 points between the best and worst candidate on that criterion alone.
  • Sebum behaviour moves every candidate identically, so it changes the numbers and decides nothing.
  • The lead rests on one criterion. Take coverage match away and a different candidate wins.

Coverage match is deciding this comparison, and you have not set the field behind it — the desk is using its own default. Set it on the profile panel and the ranking here becomes yours rather than the desk's.

Every cell, with its arithmetic

The table is the source; the figure is the summary.

The figure drops criteria that move every candidate identically, because a picture of a constant is a picture of nothing. This table keeps all of them, and prints the weight the engine used wherever it published one.

A wide spread means this desk’s model discriminates strongly on that axis. It does not mean reality does. These are weights on a preference, not measurements of a face, and no cell here is a probability.
