This is a lively and engaging look at the factors, known as `artifacts', that can confound behavioural experiments. By describing key research studies in a narrative style, Rosnow and Rosenthal address the issues of scientific method and clarify the difficulties that behavioural researchers will encounter. Their final chapter addresses ethical issues, again through narrative use of examples.
