5 Myths About Sociosexuality, Debunked

What Sociosexuality Actually Measures — And What It Doesn't

Sociosexuality is one of the most widely studied dimensions of human mating psychology, yet misconceptions about it circulate constantly — in comment sections, dating forums, and even among researchers who encounter the concept for the first time. Before you take the quiz or explore population-level patterns in the statistics, it helps to clear the air. Here are five persistent myths about sociosexuality, and why the research tells a more nuanced story.

Myth 1: A High SOI-R Score Makes You a Bad Person

This is probably the most damaging misreading of the entire framework. The Sociosexual Orientation Inventory–Revised (SOI-R) measures a psychological orientation — specifically, the degree to which a person is open to sexual relationships without close emotional commitment. It does not measure morality, character, or worth as a partner or human being.

Sociosexuality is understood by researchers as a stable individual difference, much like introversion or conscientiousness. Having an unrestricted orientation simply means a person tends to be more comfortable with casual sexual contexts. Having a restricted orientation means they tend to prefer emotional closeness before sex. Neither end of the spectrum is pathological, and neither is inherently virtuous. Framing the scale as a judgment of character misrepresents its purpose entirely and discourages honest self-reflection, which is exactly what the measure is designed to support.

Myth 2: Unrestricted People Are Inevitably Unfaithful in Relationships

This conflates a general orientation with a specific behavior in a specific context. Research distinguishes between sociosexual attitudes, desires, and behaviors as partially separable components — and behavior, especially within a committed relationship, is shaped by far more than orientation alone. Situational factors, personal values, relationship quality, and deliberate commitment all play meaningful roles.

An unrestricted person who genuinely invests in a relationship is not automatically destined to be unfaithful. Similarly, a restricted person is not automatically a reliable partner by virtue of their score. What the research does suggest is that mismatches in sociosexual orientation between partners can create tension — not because one person is "bad," but because their default comfort levels around relationship structure may differ. Understanding your orientation, and your partner's, opens space for more honest conversation rather than moral accusation.

Myth 3: Sociosexuality Is Just a Fancy Word for Promiscuity

Reducing sociosexuality to a body count fundamentally misunderstands the construct. The SOI-R captures three distinct dimensions: behavior (past sexual conduct), attitude (comfort with casual sex in principle), and desire (spontaneous attraction to people outside a current relationship). These dimensions do not always align neatly, and researchers have found that treating them as separate components reveals far more about how people actually experience their sexuality than collapsing everything into a single behavioral count.

Someone might have a history of very few sexual partners but hold open, unrestricted attitudes about casual sex in the abstract. Someone else might have had many partners but feel genuine discomfort with the idea now. Promiscuity, as a social judgment, carries moral freight that the SOI-R deliberately avoids. The instrument is designed to describe, not condemn.

Myth 4: You Can't Really Measure Something This Personal

Skepticism about psychological measurement is healthy, but in the case of sociosexuality, the evidence for validity is robust. The original Sociosexual Orientation Inventory, developed by Simpson and Gangestad, demonstrated strong convergent and discriminant validity — meaning it measures what it claims to measure and does not simply overlap with unrelated constructs. The revised version by Penke and Asendorpf improved on this further by separating the behavioral, attitudinal, and desire components into distinct subscales.

People's scores also show meaningful relationships with how they behave in real relationships, how they respond to potential partners, and how they describe their own preferences. A measure that predicted nothing and related to nothing would not have sustained two decades of productive research. The SOI-R is not perfect — no psychological instrument is — but the evidence for its usefulness is well established.

Myth 5: Sociosexual Orientation Is Fixed for Life

Orientation, as measured by the SOI-R, shows meaningful stability over time — but stability is not the same as immutability. Life experiences, relationship transitions, aging, and shifts in personal priorities can all correspond with changes in how people score. A person who moves through a period of unrestricted exploration may later find their attitudes and desires shifting toward something more restricted. The reverse is equally possible.

This is actually one of the more theoretically interesting aspects of sociosexuality: it sits at the intersection of relatively stable individual difference and genuinely dynamic lived experience. Taking the quiz at different points in your life is not a sign that the measure is unreliable — it may simply reflect that you have changed, which is among the most human things a person can do.

The Bottom Line

Sociosexuality research exists to describe human diversity, not to rank it. The SOI-R is a tool for understanding, and like any good tool, it works best when used without the weight of moral assumption.
