罗伊·鲍迈斯特

Roy Frederick Baumeister (born May 16, 1953) is an American social psychologist who is known for his work on the self, social rejection, belongingness, sexuality and sex differences, self-control, self-esteem, self-defeating behaviors, motivation, aggression, consciousness, and free will.

Education and academia

Baumeister earned his A.B. from Princeton University and his M.A. from Duke University. He returned to Princeton University with his mentor Edward E. Jones and earned his Ph.D. from the university's Department of Psychology in 1978.

Baumeister then taught at Case Western Reserve University from 1979 to 2003, serving as a professor of psychology and later liberal arts. He later worked at Florida State University as the Francis Eppes Eminent Scholar and head of the social psychology graduate program. At FSU, Baumeister worked in the psychology department, teaching classes and graduate seminars on social and evolutionary psychology. In 2016 he moved to the School of Psychology at the University of Queensland in Australia where he taught for several years.

He is a fellow of both the Society for Personality and Social Psychology and the Association for Psychological Science. Baumeister was named an ISI highly cited researcher in 2003 and 2014.

Topics of research

Baumeister's research focuses on six themes: self control, decision-making, the need to belong and interpersonal rejection, human sexuality, irrational and self-destructive behavior, and free will.

He is the most cited author of a series of psychology journals focusing on personality such as Psychological Bulletin, Journal of Personality, Personality and Social Psychology Review (T&F), Psychological Science in the Public Interest.

The self

Baumeister has conducted research on the self, focusing on various concepts related to how people perceive, act, and relate to their selves. Baumeister wrote a chapter titled, "The Self" in The Handbook of Social Psychology, and reviewed the research on self-esteem, concluding that the perceived importance of self-esteem is overrated.

Irrationality and self-defeating behavior

In a series of journal articles and books, Baumeister inquired about the reasons for self-defeating behavior. His conclusions: there is no self-defeating urge (as some have thought). Rather, self-defeating behavior is either a result of trade-offs (enjoying drugs now at the expense of the future), backfiring strategies (eating a snack to reduce stress only to feel more stressed), or a psychological strategy to escape the self – where various self-defeating strategies are rather directed to relieve the burden of selfhood.

The Need to Belong

Baumeister wrote a paper on the need-to-belong theory with Mark Leary in 1995. This theory seeks to show that humans have a natural need to belong with others. Baumeister and Leary suggest that human beings naturally push to form relationships. This push helps to distinguish a need (rather than a desire). In addition to the drive for attachment, people also struggle to avoid the disintegration of these relationships. As part of this theory, a lack of belonging would have a long-term, negative impact on mood and health, and those who do not meet their belonging needs may suffer from behavioral and psychological issues.

Need-to-belong theory has two necessary parts:

There is frequent contact between the people involved in the attachment that is typically conflict-free.

The notion of an ongoing and continued relationship between them is essential.

This work was groundbreaking in that it separated itself from previous theories relating to attachment such as those of John Bowlby. While Bowlby's theory implied the attachment needs to be applied to a group leader or authority figure, Baumeister and Leary's need-to-belong theory posited that the relationship could be with anyone. To further distinguish the two theories, Baumeister and Leary theorized that if a relationship dissolved, the bond can often be replaced with a bond to another person.

Later, Baumeister published evidence that the way people look for belongingness differs between men and women. Women generally prefer a few close and intimate relationships, whereas men generally prefer shallower connections with a greater number of people or to belong to a cause rather than close interpersonal relations.

Self-regulation

Baumeister also researched self-regulation. He coined the term "ego depletion" to describe the evidence that humans' ability to self-regulate is limited, and after using it there is less ability (or energy) to self-regulate. Ego depletion has a general effect, such that exerting self-control in one area will use up energy for further regulation in other areas of life. Further research by Baumeister and colleagues has led to the development of the Strength Model of self-control, which likens this ego depletion to the tiredness that comes from physically exerting a muscle. A corollary to this analogy, supported by his research, is that self-control can be strengthened over time, much like a muscle. The energy used up is more than metaphorical, however; his research has found a strong link between ego depletion and depletion of blood-glucose levels. Baumeister also edited two academic books on self-regulation, Losing Control and Handbook of Self-Regulation, and has devoted numerous experiments and journal papers to the topic. He also describes this research in a book, Willpower, authored with former New York Times journalist John Tierney.

In 2016, a large study carried out at two dozen labs in countries across the world that sought to reproduce the effects described in these studies was unsuccessful. Baumeister, however, disputed the protocol used in this replication. Baumeister also plans to run his own pre-registered replication using a protocol that is more in line with most ego-depletion experiments.
