A common criticism of psychology concerns its fuzziness as a science. Philosopher Thomas Kuhn's 1962 critique implied psychology overall was in a pre-paradigm state, lacking the agreement on overarching theory found in mature sciences such as chemistry and physics. Because some areas of psychology rely on research methods such as surveys and questionnaires, critics have claimed that psychology is not as scientific as many assume. Other phenomena that psychologists are interested in such as personality, thinking and emotion cannot be directly measured and are often inferred from subjective self-reports, which may be of limited use to an objectifying science.

The validity of probability testing as a research tool has been called into question. There is concern that this statistical method may promote trivial findings as meaningful, especially when large samples are used.[33] Some psychologists have responded with an increased use of effect size statistics, rather than sole reliance on the traditional p<.05 decision rule in statistical hypothesis testing.

In recent years, and particularly in the U.S., there has been increasing debate about the nature of therapeutic effectiveness and about the relevance of empirically examining psychotherapeutic strategies.[34] One argument states that some therapies are based on discredited theories and are unsupported by empirical evidence. The other side points to recent research suggesting that all mainstream therapies are of about equal effectiveness, while also arguing that controlled studies often do not take into consideration real-world conditions (e.g. the high co-morbidity rate or the experience of clinicians); that research is heavily biased towards the methods of the cognitive behavioral therapies (CBT); and that it typically under-represents minority groups.
