One important lesson of Roberts' target article may be potentially obscured for some by the title's reference to “self-experimentation.” At the core of this work, the key investigative resource is sustained and systematic observation, not experimentation, and it is deployed in a fashion not necessarily restricted to self-examination. There is an important reminder here of a strategically important, but neglected, relationship between observation and experiment.
