Posthuman

you robot by belle mellor

A posthuman is a concept originating notably in the fields of science fiction, futurology, contemporary art, and philosophy.

These multiple and interactive origins have contributed to profound confusion over the similarities and differences between the posthuman of ‘posthumanism’ (a line of philosophical reasoning) and the posthuman of ‘transhumanism’ (an intermediary form between the human and the hypothetical posthuman).

Is Google Making Us Stupid?

Technology Dependence

Is Google Making Us Stupid? What the Internet is doing to our brains’ is a magazine article by technology writer Nicholas G. Carr highly critical of the Internet’s effect on cognition. It was published in ‘The Atlantic’ magazine as a six-page cover story in 2008.

Carr’s main argument is that the Internet might have detrimental effects on cognition that diminish the capacity for concentration and contemplation. Despite the title, the article is not specifically targeted at Google, but more at the cognitive impact of the Internet and World Wide Web.

Extended Mind

David Chalmers

The Extended Mind‘ is a book in the field of philosophy of mind edited by MIT philosopher Richard Menary. It contains several papers by different philosophers. The ‘extended mind thesis’ (EMT) refers to an emerging concept that addresses the question as to the division point between the mind and the environment by promoting the view of active externalism.

The EMT proposes that some objects in the external environment are utilized by the mind in such a way that the objects can be seen as extensions of the mind itself. Specifically, the mind is seen to encompass every level of the cognitive process, which will often include the use of environmental aids.

Correlation does not imply Causation

Pirates and global warming

Correlation does not imply causation‘ is a phrase used in science and statistics to emphasize that a relationship between two variables does not automatically imply that one causes the other. The opposite belief, ‘correlation proves causation,’ is one of several questionable cause logical fallacies by which two events that occur together are claimed to have a cause-and-effect relationship.

The fallacy is also known as ‘cum hoc ergo propter hoc’ (Latin for ‘with this, therefore because of this’) and ‘false cause.’ It is a common fallacy in which it is assumed that, because two things or events occur together, one must be the cause of the other. By contrast, the fallacy, ‘post hoc ergo propter hoc,’ requires that one event occur after the other, and so may be considered a related fallacy.

Actor–observer Asymmetry

Fundamental attribution error

Actor-observer asymmetry (also actor-observer bias) explains the errors that one makes when forming attributions about behavior. When a person judges their own behavior, and they are the actor, they are more likely to attribute their actions to the particular situation than to a generalization about their personality. Yet when a person is attributing the behavior of another person, thus acting as the observer; they are more likely to attribute this behavior to the person’s overall disposition than as a result of situational factors.

People are more likely to see their own behavior as affected by the situation they are in, or the sequence of occurrences that have happened to them throughout their day. But, they see other people’s actions as solely a product of their overall personality, and they do not afford them the chance to explain their behavior as exclusively a result of a situational effect.

Fundamental Attribution Error

Attributional bias

In social psychology, the fundamental attribution error describes the tendency to over-value dispositional or personality-based explanations for the observed behaviors of others while under-valuing situational explanations for those behaviors.

The fundamental attribution error is most visible when people explain the behavior of others. It does not explain interpretations of one’s own behavior—where situational factors are often taken into consideration. This discrepancy is called the actor–observer bias. As a simple example, if Alice saw Bob trip over a rock and fall, Alice might consider Bob to be clumsy or careless (dispositional). If Alice tripped over the same rock herself, she would be more likely to blame the placement of the rock (situational).

Mere-exposure Effect

office romance by chris reed

The mere-exposure effect is a psychological phenomenon by which people tend to develop a preference for things merely because they are familiar with them. In social psychology, this effect is sometimes called the familiarity principle. The effect has been demonstrated with many kinds of things, including words, Chinese characters, paintings, pictures of faces, geometric figures, and sounds. In studies of interpersonal attraction, the more often a person is seen by someone, the more pleasing and likeable that person appears to be.

The earliest known research on the effect was conducted by Gustav Fechner in 1876. Edward B. Titchener also documented the effect and described the ‘glow of warmth’ felt in the presence of something that is familiar. However, Titchener’s hypothesis was thrown out once tested and results showed that the enhancement of preferences for objects did not depend on the individual’s subjective impressions of how familiar the objects were. The rejection of Titchener’s hypothesis spurred further research and the development of current theory.

Deaf Culture

deaf pride

Chuck Baird

Deaf culture describes the communities that are affected by deafness and which use sign languages as the main means of communication. When used as a cultural label, the word deaf is often written with a capital ‘D,’ and referred to as ‘big D Deaf’ in speech and sign. When used as a label for the audiological condition, it is written with a lower case ‘d.’ Members of the Deaf community tend to view deafness as a difference in human experience rather than a disability, preferring to be called ‘Deaf’ or ‘Hard of Hearing’ than ‘Hearing Impaired,’ which most people think is the most acceptable term today.

The community may include family members of deaf people and sign-language interpreters who identify with Deaf culture and does not automatically include all people who are hard of hearing. According to sign-language interpreter Anna Mindess, ‘it is not the extent of hearing loss that defines a member of the Deaf community but the individual’s own sense of identity and resultant actions.’ As with all social groups that a person chooses to belong to, a person is a member of the Deaf community if he or she ‘identifies him/herself as a member of the Deaf community, and other members accept that person as a part of the community.’

Happiness Economics

Happiness economics is the quantitative study of happiness, positive and negative affect, well-being, quality of life, life satisfaction, and related concepts, typically combining economics with other fields such as psychology and sociology. It typically treats such happiness-related measures, rather than wealth, income or profit, as something to be maximized.

The field has grown substantially since the late 20th century, for example by the development of methods, surveys and indices to measure happiness and related concepts. Given its very nature, reported happiness is subjective. It is difficult to compare one person’s happiness with another. It can be especially difficult to compare happiness across cultures. However, many happiness economists believe they have solved this comparison problem. Cross-sections of large data samples across nations and time demonstrate consistent patterns in the determinants of happiness.

Positive Psychology

Martin Seligman

Positive psychology is a recent branch of psychology whose purpose was summed up in 1998 by psychologists Martin Seligman and Mihaly Csikszentmihalyi: ‘We believe that a psychology of positive human functioning will arise, which achieves a scientific understanding and effective interventions to build thriving individuals, families, and communities.’ Positive psychologists seek ‘to find and nurture genius and talent’, and ‘to make normal life more fulfilling,’ not simply to treat mental illness.

The field is intended to complement, not to replace traditional psychology. It does not seek to deny the importance of studying how things go wrong, but rather to emphasize the importance of using the scientific method to determine how things go right. This field brings attention to the possibility that focusing only on the disorder itself would result in a partial concept of the patient’s condition.

Optimism Bias

Optimism

The optimism bias (also known as unrealistic or comparative optimism) is a bias that causes a person to believe that they are less at risk of experiencing a negative event compared to others. There are four factors that cause a person to be optimistically biased: their desired end state, their cognitive mechanisms, the information they have about themselves versus others, and overall mood.

The optimistic bias is seen in a number of situations. For example, people believing that they are less at risk of being a crime victim, smokers believing that they are less likely to contract lung cancer or disease than other smokers, first-time bungee jumpers believing that they are less at risk of an injury than other jumpers, or traders who think they are less exposed to losses in the markets.

Learned Optimism

Positive psychology

Learned optimism is the idea in positive psychology that a talent for joy, like any other, can be cultivated. It is contrasted with learned helplessness. Learning optimism is done by consciously challenging any negative self talk. The concept was created by psychologist Martin Seligman (who also coined ‘learned helplessness’) and published in his 1990 book, ‘Learned Optimism.’

The benefits of an optimistic outlook are many: Optimists are higher achievers and have better overall health. Pessimism, on the other hand, is much more common. Pessimists are more likely to give up in the face of adversity or to suffer from depression. In his book, Seligman invites pessimists to learn to be optimists by thinking about their reactions to adversity in a new way. The resulting optimism — one that grew from pessimism — is a learned optimism.
