single-blind

Subjects don't know

Single-blind describes an experiment where participants don't know whether they're receiving the treatment or a placebo, but the researchers do know.

This prevents subjects' expectations from influencing results while allowing researchers to observe directly: a single-blind clinical trial.

Compare double-blind, where neither party knows.
