|text= A heuristic is a strategy that ignores part of the information, with the goal of making decisions more quickly, frugally, and/or accurately than more complex methods (Gigerenzer and Gaissmaier [2011], p. 454; see also Todd et al. [2012], p. 7).<ref>{{cite journal

Heuristics are strategies based on rules to generate [[optimal decision]]s, like the [[anchoring effect]] and [[utility maximization problem]].<ref>{{Cite journal

However it can alternatively create systematic errors.<ref>{{cite journal|last=Sunstein|first=Cass|date=2005|title=Moral Heuristics|journal=The Behavioral and Brain Sciences|volume=28| issue=4 |pages=531–542| doi=10.1017/S0140525X05000099 | pmid=16209802 | s2cid=231738548 }}</ref>

The most fundamental heuristic is trial and error, which can be used in everything from matching nuts and bolts to finding the values of variables in algebra problems. In mathematics, some common heuristics involve the use of visual representations, additional assumptions, forward/backward reasoning and simplification.

	| quote = Gigerenzer (2021) [says] humans [and] other organisms evolved to acquire what he calls 'embodied heuristics' that can be both innate or learnt rules of thumb, which in turn supply the agility to respond to the lack of information by fast judgement. The 'embodied heuristics' use the mental capacity that includes the motor and sensory abilities that start to develop from the moment of birth. [...] 'dual-process theories' [...] we find it helpful to point out that one may distinguish between 'System 1 heuristics' [neuro] and 'System 2 heuristics' [neuro] (Kahneman 2011, p. 98). | doi-access = free}}</ref>
