Judgment Mirror

Write your principles

Why it matters Most people can list principles they admire. Fewer can list the ones they actually choose by. Your round 1 picks know the difference.

The lab kit has a fixed list of principles. Each option in the 12 round 1 pairs honours some of them.

from creative import mirror
for key, text in mirror.PRINCIPLES.items():
    print(key, "-", text)

mirror.predict(["fail-early"], "p3")   # "A", "B", or None on a tie

predict picks the option that honours more of your principles, and says None when they do not separate the two. mirror.prediction_score(principles, picks) returns (right, decided): of the pairs your principles decide, how many match your real pick.

Choose 2 to 4 principles you believe you hold. Choose before you run the score, and do not tune the list to raise it afterwards: a list chosen to fit the answers predicts nothing. Your round 1 picks are read from your First picks draft.

Recap Pick your principles, then see how many of your own choices they explain, and which they miss.

Your turn

Assign principles: 2 to 4 keys of mirror.PRINCIPLES. Read your round 1 picks with context.value_in("c-map-the-default/first-picks", "picks"). Write misses(principles, picks): the pair ids (in order p1 to p12, ignoring unknown ids, accepting lower-case picks) where mirror.predict gives a letter that differs from the pick; ties are skipped. Set score = mirror.prediction_score(principles, picks) and print it as "right of decided", for example "5 of 8", then print your misses.
