Anthropomorphism
Anthropomorphism is the tendency to imbue the real or imagined behavior of nonhuman agents, objects, or abstractions with humanlike characteristics, motivations, intentions, or emotions.

How the figure gets drawn
Epley, Waytz & Cacioppo (2007) propose three converging determinants. (1) Elicited agent knowledge: human self-knowledge is the richest, most accessible model of an agent, so people use it as an anchoring default when reasoning about ambiguous nonhuman behavior. (2) Effectance motivation: a drive to explain, predict, and control one's environment makes attributing a humanlike mind a useful (if inaccurate) heuristic, especially for unpredictable agents. (3) Sociality motivation: an unmet need for social connection (e.g., loneliness) increases the tendency to create humanlike agents to satisfy belonging. The Heider–Simmel demonstration and the ELIZA effect show how little stimulus input is required to trigger the inference, consistent with mind attribution being a fast default. Gray, Gray & Wegner (2007) supply the descriptive structure of what is attributed: two dimensions of perceived mind, Agency and Experience.
Competing account — There is debate over whether anthropomorphism is primarily a motivated process (sociality/effectance, per Epley et al.) versus a relatively automatic perceptual/cognitive default driven by agent-cue detection and over-application of theory-of-mind machinery. In human-robot interaction, the Roesler et al. (2021) meta-analysis shows effects depend heavily on moderators, suggesting no single mechanism produces uniform behavioral consequences; some researchers frame anthropomorphism less as a bias than as an adaptive, context-sensitive social heuristic.

Both chronic and induced loneliness increased the tendency to attribute humanlike mental states to nonhuman agents, supporting sociality motivation as a causal driver.

Anthropomorphism is a stable individual-difference trait that predicts moral concern afforded to agents, trust placed in them, and their social influence on the self.

Evidence — mixed. The core phenomenon is robust and old: people reliably attribute minds to nonhuman stimuli (Heider & Simmel 1944; the ELIZA effect). What is genuinely mixed is the downstream effect of anthropomorphic design on outcomes. Roesler, Manzey & Onnasch's meta-analysis (Science Robotics, 2021; 78 studies, ~6000 participants, 187 effect sizes) found an overall medium positive effect of anthropomorphic features but NO positive effect for perceived safety, empathy, or task performance, and effects that 'depend heavily on various moderators.' So the trait and the basic inference replicate well, while the practical 'anthropomorphism helps' claim is heterogeneous and condition-dependent — not a clean uniform effect.

The ELIZA effect — Weizenbaum's chatbot
Joseph Weizenbaum's 1966 pattern-matching program ELIZA (a mock Rogerian therapist) led users — including Weizenbaum's own secretary, who asked him to leave the room — to attribute genuine understanding and empathy to it despite knowing it was a simple script. Weizenbaum, alarmed, later wrote against the over-attribution. The episode gives 'the ELIZA effect' its name.

Google engineer Blake Lemoine claims LaMDA is sentient
In June 2022 Google engineer Blake Lemoine publicly claimed the LaMDA language model was sentient and had feelings after extended conversations; Google and mainstream AI researchers rejected the claim as anthropomorphic over-attribution to a text-prediction system, and Lemoine was placed on leave and later fired. A widely cited modern instance of anthropomorphizing an AI system.
To tell signal from noise
Re-describe the agent in purely mechanical terms (inputs, rules, outputs) and ask whether the human-mind explanation actually predicts behavior better than the mechanism explanation; recognize that loneliness, ambiguity, and a need for control inflate the inference, so discount accordingly. For AI specifically, remember that fluent, human-sounding output is evidence of training on human text, not of inner states.
Epley, Waytz & Cacioppo (2007) identify sociality and effectance motivation plus elicited agent knowledge as the levers; reducing those (or consciously substituting a mechanistic model) targets the cause. Roesler et al. (2021) show anthropomorphic cues do not reliably improve safety or task performance, so treating a humanlike interface as actually trustworthy is unwarranted.
Catch it in the act
Watch for language that grants an inanimate system a will of its own: 'the algorithm wants to', 'the model is trying to', 'my car hates the cold', 'the AI understands me', 'the market is nervous'. The tell is ascribing intention, preference, or emotion to something that only computes, reacts, or aggregates. Loneliness, unpredictability of the target, and a need to explain or control it all amplify the pull.
