DefamationDefamation, at a first approximation, is any form of communication that can injure a third party's reputation. This can include all modes of human-understandable communications: gestures, images, signs, words. It is not necessarily restricted to making assertions that are falsifiable, and can extend to concepts that are more abstract than reputation - like dignity and honour. For a communication to be considered defamatory, it must be conveyed to someone other than the defamed.
DisinformationDisinformation is false information deliberately spread to deceive people. It should not be confused with misinformation, which is false information but is not deliberate. "Fake news" has sometimes been categorized as a type of disinformation, but scholars have advised not using these two terms interchangeably or using "fake news" altogether in academic writing since politicians have weaponized it to describe any unfavorable news coverage or information.
FraudIn law, fraud is intentional deception to secure unfair or unlawful gain, or to deprive a victim of a legal right. Fraud can violate civil law (e.g., a fraud victim may sue the fraud perpetrator to avoid the fraud or recover monetary compensation) or criminal law (e.g., a fraud perpetrator may be prosecuted and imprisoned by governmental authorities), or it may cause no loss of money, property, or legal right but still be an element of another civil or criminal wrong.
Power (social and political)In social science and politics, power is the social production of an effect that determines the capacities, actions, beliefs, or conduct of actors. Power does not exclusively refer to the threat or use of force (coercion) by one actor against another, but may also be exerted through diffuse means (such as institutions). Power may also take structural forms, as it orders actors in relation to one another (such as distinguishing between a master and an enslaved person, a householder and their relatives, an employer and their employees, a parent and a child, a political representative and their voters.
