Appeal to Novelty
Treating something as true, correct, or better mainly because it is new, recent, or "modern," without independent evidence that it actually works better.
Entered into evidence“The appeal to novelty is a logical fallacy in which one prematurely claims that an idea or proposal is correct or superior, exclusively because it is new and modern.”

Novelty as its own reward (midbrain fMRI)
The substantia nigra/ventral tegmental area (SN/VTA) responded preferentially to absolute stimulus novelty rather than to negative emotion, behavioral relevance, or rarity, and novelty enhanced subsequent memory - supporting the idea that novelty acts as an intrinsic reward/learning signal.

Perceived novelty and product evaluation (inverted-U)
An inverted-U relationship: moderate novelty maximized evaluation, while high novelty reduced it (curiosity vs expectation-violation). Newer is NOT linearly better - directly undercutting a naive appeal to novelty.
Yingyue Luan, Yeun Joon Kim, 2022 · Linear novelty γ = 39.83 (p < .001); quadratic novelty² γ = -406.42 (p < .001); reputation moderation reported as γ = .35 (reputation × novelty) and γ = -9.20 (reputation × novelty²)
Final disposition
No chain of custody
Appeal to novelty itself is a logician's normative category, not an experimentally tested effect, so there is no replication record for 'the fallacy' per se. The adjacent empirical claims are mixed: novelty-as-reward neural responses replicate reasonably well, but the behavioral consequence is NOT a simple 'new is preferred' law - large-sample work (Luan & Kim, 2022) finds an inverted-U, and the broader perceived-novelty literature splits between curiosity-benefit and expectation-violation-cost streams. So any blanket claim that people robustly over-prefer the new should be reported as context-dependent, not robust.

Handling note · how it gets waved through
Two complementary accounts. (1) Affective/neural: novelty is intrinsically rewarding - novel stimuli recruit the dopaminergic SN/VTA and hippocampal circuits (Bunzeck & Düzel, 2006), so 'new' carries a positive affective tag that can be misread as evidence of quality (an affect-as-information / attribute-substitution shortcut). (2) Heuristic/normative: under time pressure or uncertainty, decision-makers substitute the easy cue 'is it new?' for the hard question 'is it actually better?', often reinforced by a cultural progress narrative equating new with improved. The Luan & Kim inverted-U shows the cue is unreliable: novelty helps only up to a point before expectation-violation costs dominate.
Competing account — Critics note appeal to novelty is a normative label (a reasoning error defined by logicians), not a measured psychological mechanism, so 'mechanism' is partly imported from the separate novelty-seeking/neophilia literature. Some novelty preference is rational (new versions often genuinely are improved; exploration has option value), so the boundary between adaptive novelty-seeking and fallacious appeal to novelty is contested and context-dependent.

Dot-com 'New Economy' overvaluation and crash
Late-1990s investors treated internet-era newness as self-justifying, urged (e.g., by press) to discount 'quaint' metrics like the price-earnings ratio. The Nasdaq peaked at 5,048.62 on March 10, 2000 with an aggregate P/E near 200, then fell roughly 78% by October 2002. The 'New Economy / this time is different' novelty narrative had also appeared in the 1920s and 1960s.

Rapid displacement of older NSAIDs by newer COX-2 inhibitors
After 1999, heavily marketed new COX-2 inhibitors (Vioxx/rofecoxib, Celebrex) rapidly replaced older, cheaper, better-established NSAIDs even in low-risk patients who could not benefit. Alexander, Dai & Stafford (Archives of Internal Medicine, Jan 25, 2005) reported most COX-2 growth from 1999-2002 went to low/very-low GI-risk patients; the drugs cost ~6x more (e.g., Vioxx $2.64/day vs ibuprofen $0.42/day per the cited Stanford release). Vioxx was withdrawn in 2004 over cardiovascular harm - a costly preference for the new over the proven.

New Coke (1985) - caution: a counter-illustration
Coca-Cola replaced its 99-year-old formula on April 23, 1985 partly to look fresh against Pepsi; consumer backlash forced a reversal after 79 days (July 11, 1985). Often cited around novelty marketing, but it more directly shows the LIMITS of assuming newer is better - a cautionary case rather than a pure appeal-to-novelty success.
To break the chain
Force a like-for-like comparison on outcomes, not age: ask 'better at what, measured how, versus the current option?' Demand the same evidence bar you'd require of the incumbent, factor in switching costs and the unproven track record of the new thing, and remember the inverted-U - moderate novelty can help but maximal novelty often violates expectations and underperforms.
Luan & Kim (2022) show evaluation peaks at moderate, not maximal, novelty (quadratic γ = -406.42, p < .001); the COX-2 case shows newer, costlier drugs (~6x the price) displaced safer proven ones in patients who could not benefit.
Catch it in the act
Watch for arguments where the load-bearing reason is the date, version number, or the word 'new/modern/next-gen/revolutionary' rather than any evidence of better outcomes - e.g. 'it's the latest, so it must be better,' 'that approach is outdated,' or 'this is the future.' Under time pressure (the 'need to act fast' quadrant), 'is it new?' quietly replaces 'is it actually better?' The tell: remove the novelty claim and no independent evidence of superiority remains.
