Judgment in the context of "Critical thinking"

Wisdom, also known as sapience, is the ability to apply knowledge, experience, and good judgment to navigate life's complexities. It is often associated with insight, discernment, and ethics in decision-making. Throughout history, wisdom has been regarded as a key virtue in philosophy, religion, and psychology, representing the ability to understand and respond to reality in a balanced and thoughtful manner. Unlike intelligence, which primarily concerns problem-solving and reasoning, wisdom involves a deeper comprehension of human nature, moral principles, and the long-term consequences of actions.

Philosophically, wisdom has been explored by thinkers from Ancient Greece to modern times. Socrates famously equated wisdom with recognizing one's own ignorance, while Aristotle saw it as practical reasoning (phronesis) and deep contemplation (sophia). Eastern traditions, such as Confucianism and Buddhism, emphasize wisdom as a form of enlightened understanding that leads to ethical living and inner peace. Across cultures, wisdom is often linked to virtues like humility, patience, and compassion, suggesting that it is not just about knowing what is right but also acting upon it.

In their most common sense, thought and thinking refer to cognitive processes that occur independently of direct sensory stimulation. Core forms include judging, reasoning, concept formation, problem solving, and deliberation. Other processes, such as entertaining an idea, memory, or imagination, are also frequently considered types of thought. Unlike perception, these activities can occur without immediate input from the sensory organs. In a broader sense, any mental event—including perception and unconscious processes—may be described as a form of thought. The term can also denote not the process itself, but the resulting mental states or systems of ideas.

A variety of theories attempt to explain the nature of thinking. Platonism holds that thought involves discerning eternal forms and their interrelations, distinguishing these pure entities from their imperfect sensory imitations. Aristotelianism interprets thinking as instantiating the universal essence of an object within the mind, derived from sense experience rather than a changeless realm. Conceptualism, closely related to Aristotelianism, identifies thinking with the mental evocation of concepts. Inner speech theories suggest that thought takes the form of silent verbal expression, sometimes in a natural language and sometimes in a specialized "mental language," or Mentalese, as proposed by the language of thought hypothesis. Associationism views thought as the succession of ideas governed by laws of association, while behaviorism reduces thinking to behavioral dispositions that generate intelligent actions in response to stimuli. More recently, computationalism compares thought to information processing, storage, and transmission in computers.

Intellect is a faculty of the human mind that enables reasoning, abstraction, conceptualization, and judgment. It enables the discernment of truth and falsehood, as well as higher-order thinking beyond immediate perception. Intellect is distinct from intelligence, which refers to the general ability to learn, adapt, and solve problems, whereas intellect concerns the application of reason to abstract or philosophical thought.

In philosophy, intellect (Ancient Greek: dianoia) has often been contrasted with nous, a term referring to the faculty of direct intuitive knowledge. While intellect engages in discursive reasoning, breaking down concepts into logical sequences, nous is considered a higher cognitive faculty that allows for direct perception of truth, especially in Platonism and Neoplatonism. Aristotle distinguished between the active intellect (intellectus agens), which abstracts universal concepts, and the passive intellect, which receives sensory input.

An expert is somebody who has a broad and deep understanding and competence in terms of knowledge, skill and experience through practice and education in a particular field or area of study. Informally, an expert is someone widely recognized as a reliable source of technique or skill whose faculty for judging or deciding rightly, justly, or wisely is accorded authority and status by peers or the public in a specific well-distinguished domain. An expert, more generally, is a person with extensive knowledge or ability based on research, experience, or occupation and in a particular area of study. Experts are called in for advice on their respective subject, but they do not always agree on the particulars of a field of study. An expert can be believed, by virtue of credentials, training, education, profession, publication or experience, to have special knowledge of a subject beyond that of the average person, sufficient that others may officially (and legally) rely upon the individual's opinion on that topic. Historically, an expert was referred to as a sage. The individual was usually a profound thinker distinguished for wisdom and sound judgment.

In specific fields, the definition of expert is well established by consensus and therefore it is not always necessary for individuals to have a professional or academic qualification for them to be accepted as an expert. In this respect, a shepherd with fifty years of experience tending flocks would be widely recognized as having complete expertise in the use and training of sheep dogs and the care of sheep.

Heuristics (from Ancient Greek εὑρίσκω (heurískō) 'to find, discover') is the process by which humans use mental shortcuts to arrive at decisions. Heuristics are simple strategies that humans, animals, organizations, and even machines use to quickly form judgments, make decisions, and find solutions to complex problems. Often this involves focusing on the most relevant aspects of a problem or situation to formulate a solution. While heuristic processes are used to find the answers and solutions that are most likely to work or be correct, they are not always right or the most accurate. Judgments and decisions based on heuristics are simply good enough to satisfy a pressing need in situations of uncertainty, where information is incomplete. In that sense they can differ from answers given by logic and probability.

The economist and cognitive psychologist Herbert A. Simon introduced the concept of heuristics in the 1950s, suggesting there were limitations to rational decision making. In the 1970s, psychologists Amos Tversky and Daniel Kahneman added to the field with their research on cognitive bias. It was their work that introduced specific heuristic models, a field which has only expanded since. While some argue that pure laziness is behind the heuristics process, this could just be a simplified explanation for why people don't act the way we expected them to. Other theories argue that it can be more accurate than decisions based on every known factor and consequence, such as the less-is-more effect.
