Adam Smith\u2019s invisible hand<\/em> is a tremendously successful metaphor. Quotes abound to state how important and pervasive the idea is (and was) for both economics and social sciences at large. Yet, the invisible hand also happens to also be a remarkably ill-defined metaphor. It seems nearly impossible to find an agreement through the literature as to what the metaphor is, exactly, or which phenomena would count as occurrences of the invisible hand. I want to suggest that the lack of a precise definition was not a problem, but the precise reason why it got so successful: it offered a versatile label that could be used to refer to causal links across scales of analysis, while avoiding to commit to any more precise mechanistic explanation. <\/p>\n\n\n\n

The invisible hand metaphor\u2019s success is especially intriguing when considering how (parsimoniously) it was used by Adam Smith. It appeared in only twice in relation to economic phenomena in his works (three times in total, the last one relates to astronomy). In the Wealth of Nations<\/em>, the invisible hand appears in the context of describing how the preference of a merchant to keep his wealth in his home country contributes to the greater good. In the Theory of Moral Sentiments<\/em>, the metaphor seems to relate to the \u2018equal\u2019 repartition of resources results from the landlord being unable to consume the totality of what is produced on his land. There have been numerous attempts to pinpoint what was meant by Adam Smith\u2019s uses of the invisible hand. Several authors (Kennedy, 2009; Grampp, 2000) also concur on the idea that the invisible hand was used by Adam Smith essentially as a rhetorical<\/em> device, and did not imply a justificatory dimension. <\/p>\n\n\n

The invisible hand metaphor did not meet success before the 1940s (see Kennedy, 2009, and Samuels, 2011), and was indeed popularized mostly by 20th century economists, who offered a large range of possible interpretations of the metaphor, and made it a scientific concept. The invisible hand has since been used, by economists and other social scientists, so with at least nine different meanings. \u00ab The invisible hand has been interpreted to mean: (1) the force that makes the interest of one the interest of others, (2) the price mechanism, (3) a figure for the idea of unintended consequences, (4) competition, (5) the mutual advantage in exchange, (6) a joke, (7) an evolutionary process, (8) providence, (9) the force that restrains the export of capital. \u00bb (Grampp, 2000, p. 450). To this list, Grampp also adds his own understanding of the invisible hand, i.e., of it then being \u00ab self-interest operating in (\u2026) the circumstance in which a private transaction yields a positive externality that augments a public good \u00bb (p. 451). An even more extensive list of candidates to be qualified as the invisible hand can be found in the third chapter of Erasing the invisible hand<\/em> (Samuels, 2011). [1] The ability of the invisible hand to fulfill any kind of epistemic role, i.e., produce any knowledge, has also been seriously called into question [2].<\/p>\n\n\n\n

Then, if this metaphor\nis both imprecise and mostly rhetoric, how did it become so successful, and\nespecially as a scientific <\/em>concept? <\/p>\n\n\n\n

I suggest that the invisible hand\u2019s importance to economics was to be found in offering a way to acknowledge the existence of causal principles and links at play in a multitude of phenomena in economics. The invisible hand metaphor is able to fulfill this function by being a metaphor of \u2018restricted\u2019 agency, and by black-boxing different parts of the economic reasoning that are crucial but nonetheless out of economic investigation\u2019s scope.<\/p>\n\n\n\n

First, the invisible\nhand shows a somewhat restricted<\/em> agency. It refers only to the hand, not to a full\nagent. The metaphor is restricted to a body part and thus to the physical\naction, with no form of \u2018thoughtful\u2019 planning. This contrasts with natural\nselection. In the case of natural selection, Darwin\u2019s argument starts with\nartificial selection and with a full blown agent being responsible for the\nselection phenomenon – he then works his way down to an agent-less natural selection\nfrom there (Burnett, 2009). In the case of the invisible hand, the metaphor\ncreates a relation between the intra-individual, psychological scale and the\naggregated (large-scale) macro level. What is observable at the macroscopic\nscale seems suggestive of an underlying cause left unexplored (i.e., the\ninvisible hand). In virtue of this particularity (being limited to the\nphysically active part of an agent and devoid of any planning), the invisible\nhand metaphor stands as a \u2018missing link\u2019 or \u2018missing cause\u2019. It stands for\nsomething unknown yet necessary within the causal frame explored by economists.\nAs such, it could be used for black-boxing a level of analysis and\nacknowledging the possibility, for some type of phenomena, to cause other types\nof phenomena. <\/p>\n\n\n\n

The invisible hand metaphor seems to operate sometimes at the intra-individual level (the preference of one given merchant), or more often, between the (micro-level) individual interests and the macro-level large-scale consequences (the relation between resources repartition and the landlord\u2019s consumption capability). Let\u2019s go back to the meanings listed by Grampp: most of them are ambiguous about the level at which the hand is supposed to act, or imply several different levels at the same time. For instance, take the \u2018force that restrains the export of capital\u2019 or \u2018competition\u2019. Both can act on the individuals\u2019 psychology, or via <\/em>larger scale economic parameters, such as interest rates or prices of given commodities. In both cases, what the invisible hand metaphor achieves is no more (but no less!) than acknowledging the plausibility of a link between the two levels that are traditionally studied within economics (micro and macro).<\/p>\n\n\n\n

Metaphors are pervasive in economics – curves drawn on chalkboards and models are metaphors to the extent that are substitutes<\/em> for real-world phenomena, like markets (McCloskey, 1995). A substitution view of the metaphor\u2019s role (Black, 1962) also implies that, by definition, finding phenomena that would be an instance of the invisible hand is an unsolvable task: the metaphor fills an otherwise empty conceptual space (also referred to as catachr\u00e8sis).<\/em> These ideas for which no words seem to exist (at least in Smith\u2019s time) are either some kind of aggregate or average of the incentives and being \u2018pushed\u2019 or \u2018led\u2019 on a behavioral course, or the effects emerging from this psychological average at macroscopic scales. Both options would have crucial roles in economic reasoning, but might not have been within the scope of what economics investigated. It black-boxed parts of economic explanations that were not relevant (for instance, detailed psychological considerations), or the precise way one scale (individual for instance) influences another scale (e.g., macroscopic), while acknowledging that those elements, while out of scope or unavailable for direct inquiry at that time,  were necessary involved in economic reasoning.<\/p>\n\n\n\n

I want to suggest that it did not matter for the invisible hand\u2019s success that no one example or definition can be given or agreed upon. The lack of precision or definition did not impede its role, on the contrary: it allowed the invisible hand to stand as a place-holder for elements that were logically necessary, yet not themselves under direct investigation- at least at that point in economics\u2019 history. Lack of precision lead to at least one other known productive scientific concept. In her analysis of research programs in molecular genetics, Evelyn Fox Keller (2002) suggested that, in the case of genes, both the action and the entity doing the action were unknown and thus the word \u2018gene\u2019, and metaphors such as gene action or genetic program fulfilled a necessary role of offering labels and black-boxing out-of-reach research questions. This was a productive use of the metaphor, to the extent that it allowed research programs to be built on and pursued. I hopefully convinced you that the invisible hand metaphor\u2019s success relied on very similar grounds: it gave a label to refer to a range of phenomena relevant to the scientific activity of economists. <\/p>\n\n\n
