The supposed Lady Macbeth effect or Macbeth effect is an alleged priming effect said to occur when response to a cleaning cue is increased after having been induced by a feeling of shame. [1] The effect is named after the Lady Macbeth character in the Shakespeare play Macbeth ; she imagined bloodstains on her hands after committing murder.
In one experiment, different groups of participants were asked to recall a good or bad past deed, after which they were asked to fill in the letters of three incomplete words: "W_ _H", "SH_ _ER" and "S_ _P". Those who had been asked to recall a bad deed were about 60% more likely to respond with cleansing-related words like "wash", "shower" and "soap" instead of alternatives such as "wish", "shaker" or "stop". [1]
In another experiment, experimenters were able to reduce choice-supportive bias by having subjects engage in forms of self-cleaning. [2]
The effect is apparently localized enough that those who had been asked to lie verbally preferred an oral cleaning product and those asked to lie in writing preferred a hand cleaning product over the other kind of cleanser and other control items. [3]
Other researchers have been unable to replicate the basic effect using larger samples. [4] [5] Replication difficulties have emerged for three out of four of Zhong and Liljenquist's original studies (i.e., Study 2, Study 3, and Study 4). [6] [ better source needed ] A meta-analysis of 15 studies examining the relationship between primes related to moral threat and cleansing preferences found a small effect, with no significant relationship evident across 11 studies conducted by researchers other than the original ones.

Social psychology is the scientific study of how thoughts, feelings, and behaviors are influenced by the real or imagined presence of other people or by social norms. Social psychologists typically explain human behavior as a result of the relationship between mental states and social situations, studying the social conditions under which thoughts, feelings, and behaviors occur, and how these variables influence social interactions.
In the field of psychology, cognitive dissonance is the perception of contradictory information and the mental toll of it. Relevant items of information include a person's actions, feelings, ideas, beliefs, values, and things in the environment. Cognitive dissonance is typically experienced as psychological stress when persons participate in an action that goes against one or more of those things. According to this theory, when two actions or ideas are not psychologically consistent with each other, people do all in their power to change them until they become consistent. The discomfort is triggered by the person's belief clashing with new information perceived, wherein the individual tries to find a way to resolve the contradiction to reduce their discomfort.
Obedience, in human behavior, is a form of "social influence in which a person yields to explicit instructions or orders from an authority figure". Obedience is generally distinguished from compliance, which is behavior influenced by peers, and from conformity, which is behavior intended to match that of the majority. Depending on context, obedience can be seen as moral, immoral, or amoral.
Hand washing, also known as hand hygiene, is the act of cleaning one's hands with soap or handwash and water to remove viruses/bacteria/microorganisms, dirt, grease, or other harmful and unwanted substances stuck to the hands. Drying of the washed hands is part of the process as wet and moist hands are more easily recontaminated. If soap and water are unavailable, hand sanitizer that is at least 60% (v/v) alcohol in water can be used as long as hands are not visibly excessively dirty or greasy. Hand hygiene is central to preventing the spread of infectious diseases in home and everyday life settings.
The anchoring effect is a cognitive bias whereby an individual's decisions are influenced by a particular reference point or 'anchor'. Both numeric and non-numeric anchoring have been reported in research. In numeric anchoring, once the value of the anchor is set, subsequent arguments, estimates, etc. made by an individual may change from what they would have otherwise been without the anchor. For example, an individual may be more likely to purchase a car if it is placed alongside a more expensive model. Prices discussed in negotiations that are lower than the anchor may seem reasonable, perhaps even cheap to the buyer, even if said prices are still relatively higher than the actual market value of the car. Another example may be when estimating the orbit of Mars, one might start with the Earth's orbit and then adjust upward until they reach a value that seems reasonable.
Water memory is the purported ability of water to retain a memory of substances previously dissolved in it even after an arbitrary number of serial dilutions. It has been claimed to be a mechanism by which homeopathic remedies work, even when they are diluted to the point that no molecule of the original substance remains, but there is no evidence for it.
Moral psychology is a field of study in both philosophy and psychology. Historically, the term "moral psychology" was used relatively narrowly to refer to the study of moral development. Moral psychology eventually came to refer more broadly to various topics at the intersection of ethics, psychology, and philosophy of mind. Some of the main topics of the field are moral judgment, moral reasoning, moral sensitivity, moral responsibility, moral motivation, moral identity, moral action, moral development, moral diversity, moral character, altruism, psychological egoism, moral luck, moral forecasting, moral emotion, affective forecasting, and moral disagreement.
Stereotype threat is a situational predicament in which people are or feel themselves to be at risk of conforming to stereotypes about their social group. It is theorized to be a contributing factor to long-standing racial and gender gaps in academic performance. Since its introduction into the academic literature, stereotype threat has become one of the most widely studied topics in the field of social psychology.
Experimental philosophy is an emerging field of philosophical inquiry that makes use of empirical data—often gathered through surveys which probe the intuitions of ordinary people—in order to inform research on philosophical questions. This use of empirical data is widely seen as opposed to a philosophical methodology that relies mainly on a priori justification, sometimes called "armchair" philosophy, by experimental philosophers. Experimental philosophy initially began by focusing on philosophical questions related to intentional action, the putative conflict between free will and determinism, and causal vs. descriptive theories of linguistic reference. However, experimental philosophy has continued to expand to new areas of research.
Choice-supportive bias or post-purchase rationalization is the tendency to retroactively ascribe positive attributes to an option one has selected and/or to demote the forgone options. It is part of cognitive science, and is a distinct cognitive bias that occurs once a decision is made. For example, if a person chooses option A instead of option B, they are likely to ignore or downplay the faults of option A while amplifying or ascribing new negative faults to option B. Conversely, they are also likely to notice and amplify the advantages of option A and not notice or de-emphasize those of option B.
Ego depletion is the controversial idea that self-control or willpower draws upon a limited pool of mental resources that can be used up. When the energy for mental activity is low, self-control is typically impaired, which would be considered a state of ego depletion. In particular, experiencing a state of ego depletion impairs the ability to control oneself later on. A depleting task requiring self-control can have a hindering effect on a subsequent self-control task, even if the tasks are seemingly unrelated. Self-control plays a valuable role in the functioning of the self on both individualistic and interpersonal levels. Ego depletion is therefore a critical topic in experimental psychology, specifically social psychology, because it is a mechanism that contributes to the understanding of the processes of human self-control. There have both been studies to support and to question the validity of ego-depletion as a theory.
Primate cognition is the study of the intellectual and behavioral skills of non-human primates, particularly in the fields of psychology, behavioral biology, primatology, and anthropology.
Priming is the idea that exposure to one stimulus may influence a response to a subsequent stimulus, without conscious guidance or intention. The priming effect refers to the positive or negative effect of a rapidly presented stimulus on the processing of a second stimulus that appears shortly after. Generally speaking, the generation of priming effect depends on the existence of some positive or negative relationship between priming and target stimuli. For example, the word nurse might be recognized more quickly following the word doctor than following the word bread. Priming can be perceptual, associative, repetitive, positive, negative, affective, semantic, or conceptual. Priming effects involve word recognition, semantic processing, attention, unconscious processing, and many other issues, and are related to differences in various writing systems. Research, however, has yet to firmly establish the duration of priming effects, yet their onset can be almost instantaneous.
Processing fluency is the ease with which information is processed. Perceptual fluency is the ease of processing stimuli based on manipulations to perceptual quality. Retrieval fluency is the ease with which information can be retrieved from memory.
The assimilation effect, assimilation bias or biased assimilation is a bias in evaluative judgments towards the position of a context stimulus, while contrast effects describe a negative correlation between a judgment and contextual information.
A number of studies have found that human biology can be linked with political orientation. This means that an individual's biology may predispose them to a particular political orientation and ideology. Many of the studies linking biology to politics remain controversial and unrepeated.Davies, James. "The Proper Biological Study of Politics". Political Psychology. 4 (4): 731–743. doi:10.2307/3791065. JSTOR 3791065.
Self-licensing is a term used in social psychology and marketing to describe the subconscious phenomenon whereby increased confidence and security in one's self-image or self-concept tends to make that individual worry less about the consequences of subsequent immoral behavior and, therefore, more likely to make immoral choices and act immorally. In simple terms, self-licensing occurs when people allow themselves to indulge after doing something positive first; for example, drinking a diet soda with a greasy hamburger and fries can lead one to subconsciously discount the negative attributes of the meal's high caloric and cholesterol content.

The replication crisis is an ongoing methodological crisis in which the results of many scientific studies are difficult or impossible to reproduce. Because the reproducibility of empirical results is an essential part of the scientific method, such failures undermine the credibility of theories building on them and potentially call into question substantial parts of scientific knowledge.
The Reproducibility Project: Psychology was a crowdsourced collaboration of 270 contributing authors to repeat 100 published experimental and correlational psychological studies. This project was led by the Center for Open Science and its co-founder, Brian Nosek, who started the project in November 2011. The results of this collaboration were published in August 2015. Reproducibility is the ability to produce the same findings, using the same methodologies as the original work, but on a different dataset. The project has illustrated the growing problem of failed reproducibility in social science. This project has started a movement that has spread through the science world with the expanded testing of the reproducibility of published works.
