An example of applying scientific skepticism involves questioning the claim that giving children a weekly allowance helps them develop financial responsibility. A skeptical approach considers alternative explanations—such as the possibility that an allowance merely teaches children to spend money or become materialistic—and demands systematically collected empirical evidence before accepting the claim.

Children's Allowance as an Example of Skepticism

A tolerance for uncertainty is the scientific acceptance that there is frequently not enough evidence to fully evaluate a claim or belief, leaving many things simply unknown. Although this lack of knowledge can cause practical difficulties in everyday decision-making, it is viewed as an exciting opportunity for future scientific research.

Tolerance for Uncertainty

What does it mean to cultivate an attitude of scientific skepticism?

Scientists cultivate an attitude of skepticism, which means pausing to consider alternatives and to search for evidence—especially systematically collected empirical evidence—when there is enough at stake to justify doing so. It does not mean being cynical, distrustful, or questioning every claim one comes across.

Schools of Thought in Epistemology

Intuition is a method of knowing where individuals rely on their instincts, emotions, and gut feelings to guide their understanding rather than examining objective facts or applying rational logic. It involves accepting a belief as true simply because it inherently feels right or because someone's behavior intuitively seems unusual, prompting the need to critically evaluate whether such subjective knowledge should be fully trusted.

Intuition

Folk psychology encompasses the intuitive beliefs and commonsense notions people naturally develop about human behavior, thoughts, and feelings. Although some of these everyday assumptions are reasonably accurate, scientific research demonstrates that many intuitive beliefs are incorrect, highlighting the necessity of a formal scientific approach to psychology.

Folk Psychology

Empirical evidence refers to information and data that has been systematically collected through scientific research and direct observation. It is the objective evidence used to evaluate alternatives and validate claims.

The view that knowledge does not exist as a singular objective truth, but rather as a collection of constructions made by humans. We can only interact with reality through our interpretation of it. No interpretation is more or less “accurate”, but rather more or less applicable/helpful to our own experiences.

Epistemic Constructivism

Empiricism is a method of acquiring knowledge that relies on direct observation and personal experience. It forms a foundational way of understanding the world based on what can be seen, heard, or otherwise sensed in the environment.

Empiricism

A school of founded on the premise that ideas, policies, and initiatives should be judge on their usefulness, workability, and practicality. It emphasizes the importance of action over dogma, of experience over set principles, and of concepts borrowing meaning from their consequences and truths for their proof. As a result, ideas are primarily tools and plans of action. 

Pragmatism

Posits that there is no actual normative role for epistemology. Epistemology does not tell individuals what they should believe; rather, its sole valid function is to describe how information, particularly scientific knowledge, is acquired. 

Naturalized Epistemology 

A school of thought that aims to investigate the role of gender in the creation of knowledge. 

Feminist Epistemology 

An approach to epistemology that revolves around epistemic justification. The central claim is that knowledge can only be seen as valid relative to a specific context, society, culture or individual

Epistemic Relativism

An approach to epistemology based on the position that knowledge is actively created by the cognising subject, rather than being passively received from the surrounding environment.

The view that knowledge is the individual's ability to contemplate the environment surrounding them, and think about the purposes of the eternal and spiritual reality they are manifested in as facts. The idealist looks for broad principles in the universe which can be elevated to the status of univeral truths. 

Epistemic Idealism 

A school of thought that attempts to deal with epistemological questions through the use of the mathematical theory of probability. It relies on the use of  probability calculus to represent degrees of belief and then applies this  same technique to challenges of belief change, confirmation, evidence, justification, and coherence. 

Bayesian Epistemology

Rationalism is a method of acquiring knowledge that relies on stating premises and following logical rules to arrive at sound conclusions. If the initial premises are correct and logic is applied appropriately, this method provides a valid means of understanding and acquiring new information.

Rationalism

Scientific Skepticism

MIPVU: First, annotators determine the contextual meaning of the target word. Then, they look up the word in a dictionary and search for a more basic meaning than the contextual meaning. If a more basic meaning exists, the contextual meaning differs from the basic meaning, and if it can be understood in comparison, then it is judged as a metaphor-related word.

Judge metaphoricity in a systematic way

A primary drawback of relying on intuition is that intuitive judgments are frequently incorrect. This vulnerability arises because instinctual decisions are driven by cognitive and motivational biases rather than being grounded in logical reasoning, objective facts, or scientific evidence.

Limitations of Intuition

Despite its limitations, intuition can occasionally be an advantageous decision-making tool. Continuously weighing every alternative and analyzing all possibilities can lead to paralyzing indecision. In such situations, making rapid choices guided by intuitive feelings can sometimes be superior to relying entirely on strict logical analysis.

Benefits of Intuition

Relying strictly on the method of authority to obtain knowledge is inherently problematic because authority figures are not infallible. They may provide incorrect information, base their conclusions on their own flawed intuition rather than empirical evidence, or possess hidden motives to mislead their audience.

Limitations of the Method of Authority

Because humans lack the natural cognitive capacity for extensive observation, memory, and complex analysis, forming perfectly accurate beliefs is nearly impossible. This cognitive limitation forces people to rely on mental shortcuts to process everyday information and form conclusions.

Cognitive Limits in Belief Formation

Confirmation bias is the cognitive tendency to selectively focus on cases that validate our pre-existing intuitive beliefs while actively disregarding or forgetting cases that contradict them. This mental shortcut leads individuals to reinforce incorrect assumptions by ignoring disconfirming evidence.

Confirmation Bias

Motivational bias is the cognitive tendency to hold onto incorrect intuitive beliefs simply because it is emotionally pleasing or comforting if they were true. People maintain these incorrect beliefs, often despite a lack of empirical evidence, because the beliefs provide hope or foster positive feelings about themselves.

Motivational Bias

Before conducting formal experiments, scientists must first formulate ideas and hypotheses to test. To generate these new concepts, researchers frequently draw upon foundational methods of knowing, including intuition, authority, rationalism, and basic empiricism, before subjecting them to rigorous scientific evaluation.

Idea Generation in the Scientific Method

An everyday example of intuition is believing that a friend is lying to you simply because she is acting strange and avoiding eye contact. This scenario illustrates how knowledge can be acquired through subjective, intuitive feelings about someone's behavior rather than objective evidence, raising the question of whether such sources should be trusted.

Example of Intuition: Friend Lying

In the context of research methods, which of the following best defines intuition as a method of knowing?

While some ideas represented in pop psychology are true, much of pop psychology is full of misinformation that is mistaken for fact by laypeople, non-psychological professionals, and even some in the mental health field.

Pop Psychology Myths

A prevalent misconception in folk psychology is that expressing anger by "letting it out"—such as screaming or punching an object—will relieve the emotion. Contrary to this commonsense belief, scientific research has demonstrated that venting anger in this manner typically leaves individuals feeling more angry rather than less.

The Catharsis Myth

A common intuitive belief is that an innocent person would never confess to a crime they did not commit unless subjected to extreme duress, such as physical torture. However, extensive empirical research contradicts this commonsense notion, revealing that false confessions are surprisingly frequent and occur for a variety of psychological and situational reasons.

The False Confessions Myth

A common misconception in popular psychology is the belief that the majority of people go through a psychological midlife crisis during their 40s or 50s. Scientific research has shown that a normative, universal midlife crisis is a myth.

The Midlife Crisis Myth

A prevalent myth in popular psychology suggests that students learn most effectively when educational methods are tailored to their specific learning styles. Scientific studies have demonstrated that matching teaching styles to learning styles is a misconception that does not improve educational outcomes.

The Learning Styles Myth

A widely held commonsense belief is that low self-esteem is a major underlying cause of various psychological problems. However, empirical research indicates that this popular psychology myth overstates the causal role of self-esteem in mental health issues.

The Low Self-Esteem Myth

A prominent myth in popular psychology and an example of an illusory correlation is the widespread belief that the moon's phases influence human behavior, such as the idea that psychiatric admissions and crimes increase during a full moon. Extensive scientific research has consistently found no such statistical relationship, and the perception of this link is likely due to attentional bias.

The Full Moon Myth

A widely held myth of popular psychology is the incorrect belief that individuals utilize only 10% of their brain's capacity. Scientific evidence has debunked this idea, showing that humans use virtually all parts of their brain.

The 10% Brain Power Myth

Which of the following best defines the concept of folk psychology?

In psychological research, information and data that have been systematically collected through scientific research and direct observation are known as ____ evidence.
