Intuition is the ability to acquire knowledge without inference and/or the use of reason. "The word 'intuition' comes from the Latin word 'intueri' which is usually translated as 'to look inside' or 'to contemplate'." Intuition provides us with beliefs that we cannot justify in every case. For this reason, it has been the subject of study in psychology, as well as a topic of interest in the supernatural. The "right brain" is popularly associated with intuitive processes such as aesthetic abilities. Some scientists have contended that intuition is associated with innovation in scientific discovery. Intuition is also a common subject of New Age writings.
Intuition in Jungian psychology 
In Carl Jung's theory of the ego, described in 1921 in Psychological Types, intuition was an "irrational function", opposed most directly by sensation, and opposed less strongly by the "rational functions" of thinking and feeling. Jung defined intuition as "perception via the unconscious": using sense-perception only as a starting point, to bring forth ideas, images, possibilities, ways out of a blocked situation, by a process that is mostly unconscious.
Jung said that a person in whom intuition was dominant, an "intuitive type", acted not on the basis of rational judgment but on sheer intensity of perception. An extraverted intuitive type, "the natural champion of all minorities with a future", orients to new and promising but unproven possibilities, often leaving to chase after a new possibility before old ventures have borne fruit, oblivious to his or her own welfare in the constant pursuit of change. An introverted intuitive type orients by images from the unconscious, ever exploring the psychic world of the archetypes, seeking to perceive the meaning of events, but often having no interest in playing a role in those events and not seeing any connection between the contents of the psychic world and him- or herself. Jung thought that extraverted intuitive types were likely entrepreneurs, speculators, cultural revolutionaries, often undone by a desire to escape every situation before it becomes settled and constraining—even repeatedly leaving lovers for the sake of new romantic possibilities. His introverted intuitive types were likely mystics, prophets, or cranks, struggling with a tension between protecting their visions from influence by others and making their ideas comprehensible and reasonably persuasive to others—a necessity for those visions to bear real fruit.
The Myers-Briggs Type Indicator (MBTI), first published in 1944, attempted to provide an empirical method of identifying a person's dominant ego function, in terms of Carl Jung's theory. Beginning in the 1960s, scientists performed studies to see if MBTI results were consistent with the assumed theory that Jungian functions exist and conflict in such a way that one of them must be dominant and the others suppressed. Every study has found that instead of people's MBTI scores clustering around two opposite poles, such as intuition vs. sensation, with few people scoring in the middle, people's scores actually cluster around the middle of each scale in a bell curve. This suggests that the Jungian polarities do not exist. Most contemporary psychological research questions the existence of Jungian functions and the MBTI's ability to tell which function is dominant.
Intuition in other psychological theories 
In more-recent psychology, intuition can encompass the ability to know valid solutions to problems and decision making. For example, the recognition primed decision (RPD) model explains how people can make relatively fast decisions without having to compare options. Gary Klein found that under time pressure, high stakes, and changing parameters, experts used their base of experience to identify similar situations and intuitively choose feasible solutions. Thus, the RPD model is a blend of intuition and analysis. The intuition is the pattern-matching process that quickly suggests feasible courses of action. The analysis is the mental simulation, a conscious and deliberate review of the courses of action.
The reliability of one's intuition depends greatly on past knowledge and occurrences in a specific area. For example, someone who has had more experiences with children will tend to have a better instinct or intuition about what they should do in certain situations with them. This is not to say that one with a great amount of experience is always going to have an accurate intuition (because some can be biased); however, the chances of it being more reliable are definitely amplified.
Intuition and spirituality 
Intuition is commonly discussed in writings of spiritual thought. Contextually, there is often an idea of a transcendent and more qualitative mind of one's spirit towards which a person strives, or towards which consciousness evolves. Typically, intuition is regarded as a conscious commonality between earthly knowledge and the higher spiritual knowledge and appears as flashes of illumination. It is asserted that by definition intuition cannot be judged by logical reasoning.
Wacthman Nee, a Chinese theologian jailed until his death by Mao, wrote "The Spiritual Man" and other books. From the Bible, he derived that the human spirit is begotten by the Holy Spirit at the moment of ones salvation through Jesus Christ. The human spirit has the attributes of Conscience, Communion, and Intuition. In this sense Intuition is "knowing what God knows", i.e. "faith". Although a human cannot completely know what the infinite God knows, a human can know with total conviction that is superior to intellectual knowledge.
Thomas Merton discussed variations of intuition in a series of essays. In describing aesthetic intuition he asserted that the artist has a subjective identification with an object that is both heightened and intensified and thereby "sees" the object's spiritual reality. In discussing Zen meditation he asserted that a direct intuition is derived through a "struggle against conceptual knowledge." An end result is "the existent knows existence, or 'isness,' while completely losing sight of itself as a 'knowing subject.'"
Rudolf Steiner postulated that intuition is the third of three stages of higher knowledge, coming after imagination and inspiration, and is characterized by a state of immediate and complete experience of, or even union with, the object of knowledge without loss of the subject's individual ego.
Empathic accuracy 
Empathic accuracy is a term in psychology that refers to how accurately one person (usually designated the perceiver) can infer the thoughts and feelings of another person (usually designated the target). It was first introduced in conjunction with a new research method by psychologists William Ickes and William Tooke in 1988. It is similar to the term accurate empathy, which psychologist Carl Rogers had previously introduced in 1957. Empathic accuracy is an important aspect of what William Ickes has called "everyday mind reading."
Contrary to popular understanding women do not seem to possess empathic abilities that men do not have. In fact, it is claimed that anyone has the potential to develop intuition as a skill set, if desired.  However research by William Ickes has shown that women are susceptible to stereotypes, and try harder in situations where they would expect to do better. In situations where they are unaware that this is expected, no improved performance is found.
Studies and claims 
Dismissing the notion that intuitive impulses arise supernaturally, one is left to assume they originate with the many innate human senses. Remnants of perception, such as a movement occurring out of the "corner of your eye" or subtle sound that would normally be ignored as background noise, could occur simultaneously. While these events could be filtered as irrelevant by the mind, their coincidental synchronicity could lead to sudden assumptions about one's surroundings, such as the feeling of being watched or followed.
Intuitive abilities were quantitatively tested at Yale University in the 1970s. While studying nonverbal communication, researchers noted that some subjects were able to read nonverbal facial cues before reinforcement occurred. In employing a similar design, they noted that highly intuitive subjects made decisions quickly but could not identify their rationale. Their level of accuracy, however, did not differ from that of nonintuitive subjects.
Law enforcement officers often claim to observe suspects and immediately "know" that they possess a weapon or illicit narcotic substances. Often unable to articulate why they reacted or what prompted them at the time of the event, they sometimes retrospectively can plot their actions based upon what had been clear and present danger signals. Such examples liken intuition to "gut feelings" and when viable illustrate preconscious activity.
Various definitions 
Intuition is a combination of historical (empirical) data, deep and heightened observation, and an ability to cut through the thickness of surface reality. Intuition is like a slow motion machine that captures data instantaneously and hits you like a ton of bricks. Intuition is a knowing, a sensing that is beyond the conscious understanding — a gut feeling. Intuition is not pseudo-science.
– Abella Arthur
Intuition (is) perception via the unconscious
– Carl Gustav Jung
INTUITION may be defined as understanding or knowing without conscious recourse to thought, observation or reason. Some see this unmediated process as somehow mystical while others describe intuition as being a response to unconscious cues or implicitly apprehended prior learning.
– Dr. Jason Gallate & Ms Shannan Keen BA
Intuition Peak on Livingston Island in the South Shetland Islands, Antarctica is named in appreciation of the role of scientific intuition for the advancement of human knowledge. When Steve Jobs returned from India he said, “The main thing I’ve learned is intuition".

Intuition makes us look at unrelated facts and then think about them until they can all be brought together under one law. To look for related facts means holding onto what one has instead of searching for new facts. Intuition is the father of new knowledge, while empiricism is nothing but an accumulation of old knowledge. Intuition, not intellect, is the 'open sesame' of yourself." p. 16.
