Keywords
๐Ÿ’กTrust
Trust is the foundational concept of the video, referring to the reliance on the integrity, strength, ability, or surety of someone or something. It is portrayed as a complex, dynamic, and indispensable element in human social interactions and relationships. The video discusses how trust is established, its role in cooperation, and its importance in both personal and professional settings. For instance, the speaker reflects on the trust their parents placed in them as a child, allowing them to play outside unsupervised, which fostered independence and social skills.
๐Ÿ’กCognitive Psychology
Cognitive psychology is the branch of psychology that studies mental processes including how people perceive the world, think, remember, and learn. The speaker, being a cognitive psychologist, investigates the processes that allow humans to coordinate and cooperate, with a particular focus on the role of trust in these processes. It is relevant to the video's theme as it provides a scientific perspective on how trust operates within our minds and social behaviors.
๐Ÿ’กSocial Neuroscience
Social neuroscience is an interdisciplinary field that combines neuroscience and social psychology to understand how the brain functions in social situations. The video mentions social neuroscience when discussing the insights that can be gained from this field about trust, such as how our brains respond to trustworthy and untrustworthy signals. It underscores the biological and neurological components that are engaged in trust-based interactions.
๐Ÿ’กBehavioral Economics
Behavioral economics is the study of the effects of psychological, cognitive, emotional, cultural, and social factors on the economic decisions of individuals and institutions. The video references behavioral economics when discussing trust as an investment of time, effort, or money, and how trust can be measured and studied within simple economic paradigms. It highlights the practical applications and consequences of trust in economic transactions and decision-making.
๐Ÿ’กFacial Features
Facial features are the individual characteristics of a person's face, such as the shape of the eyes or mouth. The video discusses how people often use facial features as cues to determine if someone is trustworthy, suggesting that there is a common agreement on what a trustworthy face looks like. However, it is also pointed out that there is no conclusive evidence that a trustworthy-looking face correlates with trustworthy behavior, indicating the complexity and potential fallibility of such judgments.
๐Ÿ’กAuthority and Competence
Authority and competence are concepts that refer to the perceived power or expertise of an individual. The video uses the Milgram experiments as an example to illustrate how people are more likely to trust and follow instructions from someone who appears to be in a position of authority or who seems competent. This highlights the potential dangers of trusting others based solely on their appearance of authority or competence without considering the ethical implications.
๐Ÿ’กReputation
Reputation is the beliefs or opinions that are generally held about someone or something. In the context of the video, reputation is discussed as a factor that influences our expectations and judgments of others. It is noted that prior information about someone can be so influential that it may cause us to ignore their actual behavior, leading to a potential misjudgment of their trustworthiness.
๐Ÿ’กDynamic Process
A dynamic process is one that is constantly changing or evolving over time. The video emphasizes that trust is not a static condition but a dynamic process that involves ongoing interactions and adjustments. It is discussed in the context of building and maintaining relationships, where trust must be continuously assessed, built upon, and sometimes repaired.
๐Ÿ’กForgiveness
Forgiveness is the act of pardoning or ceasing to hold resentment for wrongdoing. The video highlights forgiveness as a crucial aspect of maintaining trust in relationships. When trust is broken, the ability to forgive and give someone a second chance is essential for the continuation of a cooperative and beneficial relationship.
๐Ÿ’กTheory of Mind
Theory of mind is the cognitive ability to attribute mental states โ€” beliefs, desires, intentions, and knowledge โ€” to oneself and others. The video discusses the importance of perspective-taking or theory of mind in trust-based interactions. It is the cognitive skill that allows individuals to understand the thoughts and feelings of others, which is vital for forgiving, coaxing trust, and maintaining cooperative relationships.
๐Ÿ’กIndispensable
Indispensable means absolutely necessary and essential. In the video, trust is described as indispensable for human social life. It is portrayed as a fundamental component for establishing, maintaining, and repairing relationships. The video argues that trust is not a luxury but a requirement for effective social cooperation and personal well-being.
