Is evolutionary psychology telling ‘just-so stories’? The overload of hypotheses appears to vindicate this concern.
The table below compares the approximate number of major speculative hypotheses across several biology-based research fields, including evolutionary psychology, evolutionary biology, genetics, molecular biology, and cell biology. All of these disciplines are grounded in biological science, rather than sociology or cultural theory.
The numbers are comparative estimates derived from analyses using multiple AI systems. In this context, “major speculative hypotheses” refers to distinct, named hypotheses concerning specific traits, behaviors, or biological mechanisms that are actively discussed in the scientific literature. The purpose of the table is to highlight the substantial differences in both the number and specificity of such hypotheses across these biological disciplines.

The dramatically higher number of major speculative hypotheses in evolutionary psychology has fueled one of the field’s most persistent criticisms: that many of its explanations amount to ‘just-so stories.’ Coined by critics like Stephen Jay Gould, the term refers to plausible but potentially untestable or post-hoc adaptive narratives that can be crafted for nearly any human trait or behavior. While evolutionary psychologists argue that these hypotheses generate testable predictions (unlike Kipling’s whimsical tales), the sheer volume invites scrutiny about whether some prioritize storytelling over rigorous falsification.
If a field can generate hundreds of plausible adaptive explanations for observed behaviors, but has limited means of decisively falsifying them, then narrative fit can begin to substitute for empirical constraint. The result is not necessarily false theories, but a research landscape in which speculation accumulates faster than it can be reliably pruned. A high number of competing, trait-specific adaptive hypotheses can indicate that explanations are easier to generate than to rule out, allowing plausible narratives to multiply in the absence of strong constraints. Evolutionary psychology has generated a remarkable number of hypotheses about human behavior, but this proliferation is partly driven by certain reasoning pitfalls, of which two are outlined below.
Affirming the consequent: This is a logical fallacy in which a specific observation is taken as proof of a proposed cause. In evolutionary psychology, this often looks like: “If a trait evolved for a specific purpose, we should see it today. We do see it today. Therefore, it must have evolved for that purpose.” While intuitively appealing, this reasoning is weak because the same observation could arise from many alternative causes. Yet it forms the backbone of many evolutionary “just-so” stories, making it easy to generate new hypotheses without strong empirical constraints.
Presentism: This compounds the same tendency by interpreting modern human behaviors as direct windows into ancestral adaptations. Because our current environment differs dramatically from that of our hunter-gatherer ancestors, almost any behavior can be framed as an adaptive legacy. This encourages speculative explanations, where contemporary traits—cultural, social, or even maladaptive—are recast as evolutionary imperatives.
Together, these approaches make it easy to craft “just-so” stories, even when alternative explanations exist.
This speculative lens encourages ever more evolutionary explanations, many of which are difficult to falsify. Compared with other biology-based disciplines where mechanisms are directly testable and constrained, human behavior is proven to be complex, context-dependent, and historically distant. In evolutionary psychology, however, the combination of affirming the consequent and presentism has created fertile ground for endless adaptive storytelling, fueling both fascination and debate in the field.
Cross-cultural evidence of contemporary behaviors does not prove evolutionary history. Modern traits can emerge from culture, environment, or chance, yet they are often framed as adaptive legacies. Retain this axiom if you to keep some healthy skepticism intact:
The term “hypergamy,” traditionally rooted in marital or caste-based unions, has been extended in evolutionary psychology (EP) and lay discourse to describe women’s preferences for higher-status or higher-value partners in non-marital contexts like dating, short-term mating, serial pairings, or infidelity.
Based on publication timelines and archival searches, the earliest documented uses appear in lay manosphere writings from 2007–2008, predating explicit EP academic adoption by several years. EP’s application emerged around 2008, with growth in the 2010s tied to digital dating data and mate-switching models. Below, I outline the first identified authors, focusing on explicit uses in non-marital frames.
Manosphere bloggers and forums adapted “hypergamy” early to explain women’s “branch-swinging” (trading up in casual dating or relationships) and “dual mating strategies” (short-term sex with high-value “alphas” vs. long-term provisioning from “betas”), often drawing loosely on EP but without academic rigor. This popularized the term in online dating culture.
These lay uses exploded post-2012 via Reddit’s r/TheRedPill, reframing hypergamy as an “evolved hindbrain” trigger for app-based dating and infidelity, often with misogynistic overtones (e.g., “AF/BB” for casual sex dynamics).
EP adopted the term more cautiously, initially for marital preferences, but shifted to non-marital uses in the late 2000s with studies on dating selectivity and infidelity. Earlier EP works (e.g., Buss 1989) described the pattern without the word.
Subsequent EP works, like the 2015 Mate Switching Hypothesis (Buss et al.), built on this, framing hypergamy as “trading up” in serial dating or affairs. Usage grew with online dating studies (e.g., 2020 Oxford Handbook of Evolutionary Psychology on app-based hypergamy in hookups).

In summary, lay manosphere authors like Roissy pioneered the explicit non-marital extension around 2007, influencing PUA/redpill dating advice, while EP academics formalized it in 2008 research studies. This parallel development shows cultural bleed: manosphere amplified a simplified version, later echoed in casual EP discussions.

The term hypergamy first appears in sociological and anthropological studies of marriage systems.
It described marrying up in caste or class, particularly in South Asian kinship structures (e.g., anuloma marriages).
The term was strictly confined to marriage, not mating or sexual choice.
Sociologists expanded the term to marital patterns such as:
educational hypergamy
income hypergamy
Still exclusively about marital unions, not dating or sex.
EP researchers discussed female preferences for resources, status, or dominance.
But they did not originally use the term “hypergamy”—they spoke of mate preference, mate choice, or resource-acquisition preferences.
Online writers and early Manosphere blogs began borrowing “hypergamy” from sociology, often incorrectly assuming it meant any form of women choosing the highest-status male.
The nuance that the term is marriage-specific in origin was lost.
Popular accounts of EP (e.g., YouTubers, bloggers, “red-pill” forums) adopted “hypergamy” as a catch-all for non-marital female mating behavior.
This created a disconnect between:
the literal etymology (marriage),
the academic use (marriage),
and the new pop-EP usage (sexual or romantic preference in any context).
The result is a large-scale catachresis: a word misapplied to a domain to which it does not belong.
“Hypergamy” sounds more scientific than “preference for higher-status partners.”
Very few people check etymology.
The term gained memetic traction in online male-strategy communities.
A whole generation of EP enthusiasts now uses a marriage-only word to describe non-marital mating behavior, undermining clarity.
The term hypergamy originally emerges in anthropological research on marriage systems.
It describes marrying upward in caste or class hierarchies, especially in South Asian kinship structures.
It applies exclusively to marriage, not sexual behavior, not dating, not mate preference.
The term expands to describe marital unions such as:
educational hypergamy
income hypergamy
Again: strictly marital.
Researchers studied female mate preferences for resources, status, dominance, and protection, but:
They did not use the word “hypergamy.”
Instead, they described mate choice or resource-acquisition preferences.
Bloggers and early “red-pill” communities encountered the word hypergamy in sociological texts and misinterpreted it as meaning:
“Women always prefer the highest-status man.”
The marriage-specific nature of the term was lost.
The term spread memetically through:
blogs
forums
YouTube commentary
popular EP explainers
A term that had always meant “marrying upward” was suddenly being used to describe non-marital mating and sexual behavior, creating a large-scale conceptual mistake.
This widespread misuse is an example of catachresis—using a word in a way that contradicts its actual meaning or domain.
Hypergamy derives from Greek gamos = marriage.
It does not refer to sexual choice.
It does not refer to attraction.
It does not refer to dating, hookups, or general mate preference.
Using a marriage-specific term to describe general sexual or romantic behavior is a category mistake. It is like trying to describe casual sex with the word “matrimony” ; the semantic field simply does not match.
Hypergamy = hyper + gamos
hyper- = upward
gamos = marriage
The literal meaning is:
“Upward marriage.”
Historically, academically, and etymologically, this term belongs to:
caste-marriage systems
class-based marital mobility
formal marital unions
sociological studies of marriage patterns
It does not belong to:
dating
short-term mating
hookups
sexual attraction
romantic preference
evolutionary mate choice contexts
The modern evolutionary-psychology usage is therefore incorrect.
Evolutionary psychology does not focus primarily on marriage, but on mating strategies:
short-term mating
long-term mating
sexual preferences
romantic attraction
mate competition
extra-pair mating
resource-based selection
These behaviors are much older than marriage, which is a relatively recent cultural institution.
So EP is fundamentally describing mate choice, not marriage choices.
The everyday statement:
“Women prefer the highest-status man available.”
…describes a mating preference, not a marriage rule.
Thus the term “hypergamy” is inappropriate for EP’s purposes.
If we need a term to describe female upward mate preferences across all relational contexts—sexual, romantic, or marital—then we need a term built from the correct root.
That term already exists: hypergyny.
gyne = woman
NOT marriage
Unlike gamos, it has no marital connotation.
“A woman moving upward.”
Hypergyny therefore correctly refers to:
any upward-directed female mate preference
attraction to higher-status or higher-resource males
upward selection in dating, mating, romance, or sex
It describes the very thing EP commentators mean without importing the erroneous assumption of marriage.
| Term | Root | Literal meaning | Proper domain | Accurate for EP’s female mating strategy? |
|---|---|---|---|---|
| Hypergamy: | gamos = marriage | “Upward marriage” | Marriage systems, caste/class unions | No. Using it for general mating is catachresis. |
| Hypergyny: | gyne = woman | “Woman moving upward” | Any female upward-oriented choice | Yes. Matches EP’s concept of status-oriented mate choice. |
The modern discourse on female mating strategies has been built on a linguistic mistake.
Hypergamy has always meant upward marriage.
Evolutionary psychology is about mate choice, not marriage systems.
The popular EP usage of “hypergamy” is therefore a misuse, a category error, and a clear case of catachresis.
The scientifically and linguistically correct term is:
—female upward mate preference across all sexual and romantic contexts.
Correcting this terminology not only improves clarity but also prevents the confusion that occurs when marriage-specific words are used to describe non-marital mating behavior.
The following excerpt is from the book Marriage and love in England: Modes of reproduction 1300-1840, by Alan Macfarlane (1986).
Several human populations show little to no evidence of the classic ~2:1 female-to-male reproductive skew (i.e., female Ne = 2× male Ne), and in a few cases, the pattern is reversed (male Ne > female Ne). These exceptions are crucial because they prove the skew is not a universal biological law of human mating (e.g., inevitable female hypergamy or male disposability), but a cultural and historical contingency.

Takeaway Argument
This destroys the evosimp/red-pill appeal to “genetic inevitability”. The data shows social structure, not female choice or male competition, is the primary driver.
“Twice as many women as men reproduced in our evolutionary past. That proves women are hypergamous—choosy gold-diggers who only sleep with the top 20% of men.”
Wrong.
The reproductive skew—the fact that ~80% of ancestral females left descendants while only ~40% of males did—is real.
But it is not evidence of female mate choice.
It is not evidence of hypergamy.
It is not even evidence that women had any say in the matter.
|
Genetic Fact
|
What It Means
|
|---|---|
|
Female effective population size = 2× male
|
Twice as many women as men contributed genes to the next generation.
|
|
~80% females reproduced
|
Almost every woman who reached adulthood had kids.
|
|
~40% males reproduced
|
Most men died genetic dead-ends.
|
That’s it.
That’s all the DNA tells us. It says nothing about why.
These are not edge cases.
They are the rule in 85% of documented societies (Murdock’s Ethnographic Atlas).
|
Argument
|
Reality Check
|
|---|---|
|
“Women evolved to pick high-status men.”
|
Sure—if they had the power. Most didn’t.
|
|
“Modern surveys show women want rich guys.”
|
Modern women have options. Ancestral women often had none.
|
|
“Dating apps prove the 80/20 rule.”
|
Apps are opt-in, anonymous, urban, post-feminism. Not Paleolithic.
|
Effective population size (Ne): Female Ne = 2× male Ne.
Translation: Twice as many unique mothers as fathers.
Possible causes:
The relative influence of each of these factors varies across cultures, time periods, and ecological conditions.
Buss’s work is about modern mate preferences, not ancestral monopolization.
He never says the skew “proves” hypergamy — that’s a post-hoc fan fiction by gynocentric ideologues.
Reproductive skew is evidence of asymmetric mating outcomes, not asymmetric agency. It shows some men monopolized sex—but reveals nothing indicating that women chose them freely. For this reason, we can stop letting evosimps weaponize a Y-chromosome statistic to guilt men into pandering to modern female narcissism under the false banner of “natural” hypergamy.
