Famous psychologist of the 21st century

Though we can cite instances of scientists and philosophers “doing” psychology as far back as ancient times, and psychological questioning picked up during the Enlightenment period in Europe, psychology did not emerge as a formal field of study and experimentation until around the 1830s. Nevertheless, psychology is a uniquely modern field, always growing, shifting, and adding to its scope. Most people have taken a psychology class, whether in college or high school, but many are not aware of how present psychology is in many aspects of our lives.

Psychology is so much more than just the “study of the mind.” The most influential people in psychology dive deep into niche studies, often crossing disciplines, and producing results that affect concepts as fundamental as the language we use in regular speech, and as overarching as how we understand memory and cognitive behavior. Even if you have no interest in the field beyond your 101 experience, psychology has plenty to tell you about yourself.

The following 25 people are the most influential working in psychology today. Through professorship, writing and publication, editing journals and anthologies, activism, and public discourse they have all played a major role in molding the state of the field, as well as law, technology, education, media, and your daily life. Some are certainly not here without controversy.

In what follows, we look at influential psychologists over the last decade. Based on our ranking methodology, these individuals have significantly impacted the academic discipline of psychology within 2010-2020. Influence can be produced in a variety of ways. Some have had revolutionary ideas, some may have climbed by popularity, but all are academicians primarily working in psychology. Read more about our methodology.

Note: This isn’t simply a list of the most influential psychologists alive today. Here we are focused on the number of citations and web presence of scholars in the last 10 years. There are other highly influential scholars who simply haven’t been cited and talked about as much in the last 10 years, whereas some new faces have been making a splash in the news, speaking events, and publishing, publishing, publishing. Our AI is time sensitive. To find some of the big names you might have expected to see here, we encourage you to use our dynamic ranking system and check influence over the past 20 and 50 years.

Daniel Kahneman

Daniel Kahneman Daniel Kahneman
(1934 –   )
Tel Aviv, British Mandate of Palestine

Areas of Specialization: Cognitive Biases, Behavioral Economics, Prospect Theory, Loss Aversion

Daniel Kahneman is an Israeli-American psychologist and economist who is currently Professor Emeritus of psychology and public affairs at Princeton University’s Woodrow Wilson School. Kahneman is world-famous for his groundbreaking work on the psychology of judgement and decision making. He won the Nobel Prize in Economics for his work on human rationality in economic theory in 2002.

Kahneman, along with his colleague Amos Tversky, is widely known for his work on the cognitive basis of human error stemming from heuristics and biases, which humans use as ordinary aids in decision making. Kahneman’s work (with Tversky) led to his development of prospect theory in the late 1970s. More recently, Kahneman published a popular version of his lifetime of work on errors in cognition in his 2011 best-seller Thinking, Fast and Slow. Kahneman is also known for his work in hedonic psychology, a subfield of psychology focuses on what makes us happy (or unhappy), and leads to fulfillment.

In addition to winning the Nobel Prize, Kahneman has been the recipient of numerous awards and distinctions. He was elected a member of the National Academy of Sciences in 2001. In 2007, he received the American Psychological Association’s Award for Outstanding Lifetime Contributions to Psychology, recognizing his significant contributions to the field of Psychology. For two consecutive years, in 2011 and 2012, he made the Bloomberg 50 most influential people in global finance.

Albert Bandura

Albert Bandura Albert Bandura
(1925 – 2021)
Mundare, Alberta, Canada

Areas of Specialization: Cognitive Psychology, Social Psychology, Social Cognitive Theory

Before his passing in July 2021, Albert Bandura held the title of David Starr Jordan Professor Emeritus of Social Science in Psychology at Stanford University. A top name in social psychology, Bandura was born in Mundare, Alberta, Canada, and earned his bachelor of arts at the University of British Columbia in 1949. He soon moved to the U.S. and earned his MA in 1951 and PhD in 1952 at the University of Iowa. Bandura began teaching at Stanford in 1953.

Bandura is among the most cited psychologists in the (relatively) short history of the field. He is considered the founder of social learning theory, and groundbreaking model for understanding human social development. From his famous “Bobo doll experiment”, Bandura developed his theory of how humans imitate the behaviors they observe in others as a kind of “social learning,” i.e. learning what they can and cannot do in social settings. In particular, Bandura was interested in how children learn from the behaviors they observe in adults, especially aggression. This eventually led to the development of social cognitive theory, which examines how social learning affects cognition itself, not just behavior. This has had profound effects on everything from the field itself, to education, entertainment, rehabilitation, and training.

Notable works from Bandura include Self-Efficacy in Changing Societies, Self Efficacy: The Exercise of Control, and Moral Disengagement: How People Do Harm and Live with Themselves.

For his work, Bandura has received numerous awards and honors, including fellowship with the American Academy of Arts and Sciences, the Award for Distinguished Scientific Contributions from the American Psychological Association, the Thorndike Award for Distinguished Contributions of Psychology to Education, the Lifetime Achievement Award from the Association for the Advancement of Behavior Therapy, and several handfuls of honorary doctorates.

(1962 –   )
Edmonton, Alberta, Canada

Areas of Specialization: Social Psychology, Personality

Jordan Peterson is a Canadian clinical psychologist. He is Professor of Psychology at the University of Toronto, Canada. Peterson became a household name in Canada, the United States, and indeed around the world for his invocation of free speech rights regarding the use of preferred pronouns by students at the University of Toronto. He received his bachelor’s degrees in Political Science and Psychology from the University of Alberta, and his Ph.D. in Clinical Psychology from McGill University.

Since 2016, when Peterson began broadcasting on YouTube his principled opposition to Canada’s Bill C-16, “An Act to amend the Canadian Human Rights Act and the Criminal Code,” Peterson has risen from an academic professor doing research and teaching clinical psychology to a media sensation. He lectures and gives talks regularly on topics such as abnormal, social and personality psychology and has attracted a large following online (numbering in the millions) for his content on personal growth, taking responsibility, as well as the significance of traditional belief systems for psychological health and growth. His book 12 Rules for Life: An Antidote to Chaos, which came out in 2018, was a best-seller. Peterson is also known for his critical stance toward political correctness, which he views as potentially corrosive to open dialogue and healthy society.

Peterson was also a post-doctoral researcher at McGill University and an associate professor of psychology at Harvard University, where he performed research on rises in aggression from drug and alcohol abuse. His intellectual interests range widely; he is also interested in the rise of totalitarian governments and has studied the Cold War period in the West as well as the totalitarian regimes of the Soviet Union and Nazi Germany. He counts among his major influences the pioneering psychologist Carl Jung.

James Alcock

James Alcock James Alcock
(1942 –   )
Central Butte, Saskatchewan, Canada

Areas of Specialization: Parapsychology, Social Psychology, Psychotherapy

James Alcock is a skeptic, a Canadian educator, and Professor of Psychology at York University in Canada. Alcock is most known for his critical stance towards parapsychology, the study of psychic phenomena like extrasensory perception (telepathy, precognition, clairvoyance, psychokinesis, and psychometry), as well as other purported unexplained reports like near death experiences. Alcock received his Bachelor of Science degree in physics at McGill University, and his Ph.D. at McMaster University.

Alcock’s career in psychology has been largely an attempt to root at pseudoscientific claims that, if accepted, would become a scientific study in psychology. Notably, he is a Fellow and Member of the Executive Council for the Committee for Skeptical Inquiry. He is on the Editorial Board of The Skeptical Inquirer magazine, where he also frequently contributes. Alcock has been so outspoken and successful as a critic of the paranormal that in 1999 a panel voted him one of the top skeptics of the 20th century! Perhaps ironically, he is also an accomplished amateur magician.

Alcock’s book Parapsychology-Science Or Magic?: A Psychological Perspective, published in 1981, as a major factor in psychologist Chris French’s “conversion” to skepticism about paranormal claims in terms of accepted science in psychology.

Philip Zimbardo

Philip Zimbardo Philip Zimbardo
(1933 –   )
New York City, New York, USA

Areas of Specialization: The Lucifer Effect, Time Perspective Therapy, Social Intensity Syndrome

Philip Zimbardo holds the title of Professor Emeritus at Yale University, and previously taught at Columbia University, New York University, and Yale University. In 1954, Zimbardo earned his BA in psychology, sociology, and anthropology from Brooklyn College, and completed his MS and Ph.D. in psychology at Yale University in 1959.

Zimbardo is best known for his infamous 1971 Stanford prison experiment, and what he termed “The Lucifer Effect,” discussed in the book of the same name. The experiment was received with controversy and criticism, both in terms of ethics and scientific rigor. Regardless, Zimbardo’s findings argue, in summary, that imbalances of power between people lead to corruption and abuse. Later, amid the fallout of the 2004 Abu Ghraib Prison torture scandal, Zimbardo published The Lucifer Effect: Understanding How Good People Turn Evil, examining the issue and reflecting what he found in his experiment. The book on the subject was popular among mainstream audiences, and remains a regular point of discussion in both college psychology and ethics courses. Other published works by Zimbardo include The Time Paradox which discusses the psychological science of time.

For his work, Zimbardo has received a variety of honors and awards, including the Gold Medal for Lifetime Achievement in the Science of Psychology from the American Psychological Foundation, and an honorary doctorate degree from SWPS University in Warsaw.

Jean Decety

Jean Decety Jean Decety
(1960 –   )

Areas of Specialization: Cognitive Psychology, Social Decision Making

Jean Decety is an American and French neuroscientist who is currently the Irving B. Harris Distinguished Service Professor at the University of Chicago. His area of specialty is in cognitive neuroscience and psychology, including social, affective, and developmental neuroscience. Decety received three advanced degrees in neuroscience, cognitive psychology, and biomedical engineering from Claude Bernard University Lyon 1 in France. He also received his Ph.D. from Bernard.

Decety’s research focuses on the neurobiological and psychological mechanisms involved in social decision making, and motivations for moral behavior such as empathy and attributions of justice. In particular, he explores the evolutionary underpinnings of empathy, including how it develops in young children. For his work on morality, he is interested in the phenomenon of generosity as it develops in early childhood and is expressed in a society. Importantly, Decety believes that technologies like functional neuroimaging (fMRI, for example) can help illuminate how traditional concepts like morality (empathy, generosity, or justice) are manifest in the brain. Decety’s work integrates psychological research with modern neuroscientific techniques and research, and is regarded as an exciting frontier in psychology (and neuroscience).

Decety has been the founder and editor-in-chief of the journal Social Neuroscience. He also serves on the editorial boards of Development and Psychopathology, The European Journal of Neuroscience, The Scientific World Journal, Frontiers in Emotion Science, and Neuropsychologia. Decety along with colleague John Cacioppo created the Society for Social Neuroscience in 2010.

Daryl Bem

Daryl Bem Daryl Bem
(1960 –   )

Areas of Specialization: Social Psychology, Self-Perception Theory

Daryl Bem holds the title of Professor Emeritus at Cornell University. Previously, Bem has held professorial roles at Stanford University, Harvard University, and Carnegie Mellon University. Bem was initially a student of physics, and earned his BA in the field at Reed College. Bem soon went to Massachusetts Institute of Technology, but decided to change his career path to psychology after becoming inspired by the Civil Rights Movement.

An influential figure in social psychology, Bem is perhaps best known for developing self-perception theory. Through this approach, Bem theorizes on how our attitudes and perceptions of ourselves, not just in relation to others, but within ourselves. Bem argues that our own behaviors alter our self-perceptions, but through a kind of cognitive dissonance, we reconcile these altered views as part of a self-perception that we have always held. Moreover, Bem is known for two controversial views, both of which were generally criticized for lacking scientific rigor. The first is his exotic becomes erotic theory, which attempts to explain non-heteronormative sexual attraction from childhood developments. The second is his views on the legitimacy of PSI and ESP (parapsychology), which he defended in his “Feeling the Future” article in the Journal of Personality and Social Psychology.

Bem is a fellow of the American Psychological Association, as well as the Association of Psychological Science Parapsychological Association.
