The best method for controlling placebo effects in both the subject and the experimenter is **C. double blind conditions**.
In a double blind study, neither the participants nor the experimenters know who is receiving the treatment or the placebo, which helps to minimize bias and the influence of expectations on the outcomes. This approach is particularly effective for controlling placebo effects.
