Yhprum's Law
Yhprum's law is the opposite of Murphy's law. The simple formula of Yhprum's law is: "Everything that can work, will work." "Yhprum" is "Murphy" spelled in reverse. A more specific formulation of the law by Richard Zeckhauser, a professor of political economy at Harvard University, states: "Sometimes systems that should not work, work nevertheless." Resnick ''et al''. (2006) used this law to describe how intensive and seemingly altruistic participation by giving ranking is observed in the eBay feedback system. Jøsang, in a discussion of online trust management, suggests that all similar "trust and reputation systems" are manifestations of Yhprum's law. He states the law in a similar form to Zeckhauser: "Something that shouldn't work sometimes does work." Arenas ''et al.'' in a similar discussion add the adjunct "...or at least work fairly well" to the law. Origin Although Zeckhauser is often credited with coining, the first reference to Yhprum's law may have been by Alan Abel ...

Altruistic
Altruism is the principle and moral practice of concern for the welfare and/or happiness of other human beings or animals, resulting in a quality of life both material and spiritual. It is a traditional virtue in many cultures and a core aspect of various religious and secular worldviews. However, the object(s) of concern vary among cultures and religions. In an extreme case, altruism may become a synonym of selflessness, which is the opposite of selfishness. The word "altruism" was popularized (and possibly coined) by the French philosopher Auguste Comte in French, as ''altruisme'', for an antonym of egoism. He derived it from the Italian ''altrui'', which in turn was derived from Latin ''alteri'', meaning " other people" or "somebody else". Altruism in biological observations in field populations of the day organisms is an individual performing an action which is at a cost to themselves (e.g., pleasure and quality of life, time, probability of survival or reproduction), ...
