The recommendation tide

Can recommendations change the evidence used for the next recommendations?

Make your own investigation

Compare two exposure policies from the same starting counts for five rounds.

Each round adds ten exposures. Mix proportional popularity with a uniform exploration share, then feed those exposures into the next round.

Case cards

Cut these cards apart. Use the original example first, then let a partner supply a changed case. Keep sealed/final cards with the teacher until the learner commits a rule.

Case 1

Topic: Reef

Starting count: 8

My prediction and reason:

Case 2

Topic: Bush

Starting count: 2

My prediction and reason:

Case 3

Topic: Sky

Starting count: 1

My prediction and reason:

What this cannot establish

This is a deterministic feedback model; exposure is not a measured human preference.
