New research into our 'creepiness detector' explains a lot.
"That guy is so creepy," we occasionally say about other people. But
what does that really mean and why do we say it? Our “creepy” reaction
is both unpleasant and confusing, and according to one study (Leander,
et al, 2012), it may even be accompanied by physical symptoms such as
feeling cold or chilly. Following casual conversation with colleagues
about the psychology underlying creepiness, I decided explore what's
been studied about the phenomenon. Given how frequently creepiness is
discussed in everyday life, I was amazed that no one had yet studied it
in a scientific way. The little bit of research that was at all relevant
focused on how we respond to things such as weird nonverbal behaviors,
and being socially excluded. These studies did not use the word
creepiness, but their results implied that our “creepiness detector” may in fact be a defense against some sort of threat.
Creepiness may be related to the “agency-detection” mechanisms
proposed by evolutionary psychologists. These mechanisms evolved to
protect us from harm at the hands of predators and enemies. If you are
walking down a dark city street and hear the sound of something moving
in a dark alley, you will respond with a heightened level of arousal and
sharply focused attention and behave as if there is a willful “agent”
present who is about to do you harm. If it turns out to be just a gust
of wind or a stray cat, you lost little by over-reacting, but if you
failed to activate the alarm response and a true threat was present, the
cost of your miscalculation could be high.
We evolved to err on the side of detecting threats in such ambiguous situations.
What, then, does our creepiness detector warn us about? It cannot
just be a clear warning of physical or social harm. A mugger who points a
gun in your face and demands money is terrifying. A rival who threatens
to destroy your reputation by revealing secret information about you
fills you with dread. Most of us would not use the word “creepy” to
refer to either of these situations, yet in both cases there is no
ambiguity about the presence of threat. I believe that creepiness is
anxiety aroused by the
ambiguity of whether there is something to
fear, and/or by the ambiguity of the precise
nature of the threat—sexual, physical violence, or contamination, for example—that might be present.
Only when we are confronted with
uncertainty about threat do we get “creeped out."
Our
uncertainty paralyzes us about how to respond. For example, it would be
considered rude, and strange, to run away in the middle of a
conversation with someone is sending out a creepy vibe but is actually
harmless; it could be perilous to ignore your
intuition
and engage with that individual if he is dangerous. This ambivalence
may leave you frozen in place, wallowing in creepiness. Yet this
reaction could still be adaptive if it helps you maintain vigilance
during such periods of uncertainty and manage the balance between
self-preservation and social obligation.
I began to identify the components of creepiness. Since there was no
previous body of research to build upon, I decided to pursue this
question in a study with one of my students, Sara Koehnke. Our study was
unavoidably exploratory in nature, but we had a few hypotheses:
- If creepiness communicates potential threat, males should be
more likely to be perceived as creepy than females, since males are
generally more violent and physically threatening to more people (see
McAndrew, 2009).
- Related to the first prediction, females should be more likely than males to perceive some sort of sexual threat from a "creepy" person.
- Occupations that signal a fascination with threatening stimuli, such as death or "non-normative" sex, may attract individuals that would be comfortable in such a work environment. Hence, some occupations should be perceived as creepier than other occupations.
- Since we hypothesize that creepiness is a function of uncertainty
about threat, non-normative nonverbal behaviors and behaviors or
characteristics associated with unpredictability will be positively
associated with perceptions of creepiness.
We recruited volunteers to fill out an online survey through
Facebook,
and ended up with a sample of 1,341 individuals (1,029 females, 312
males) ranging in age from 18 to 77 with a mean age of 28.97 (SD =
11.34). In the first section of the survey, our participants rated the
likelihood that a hypothetical “creepy person” would exhibit 44
different behaviors, such as unusual patterns of eye contact or physical
characteristics like visible tattoos. In the second section of the
survey, participants rated the creepiness of 21 different occupations,
and in the third section, they simply listed two hobbies that they
thought were creepy. In the final section, participants expressed their
level of agreement with 15 statements about the nature of creepy people.
Our study confirmed the following:
- Perceived creepy people are more likely to be males than females.
- Females are more likely to perceive sexual threat from creepy people.
- Occupations do differ in level of perceived
creepiness. Clowns, taxidermists, sex-shop owners, and funeral directors
were at the top of the list.
- Unpredictability is an important component of perceived creepiness.
- A variety of non-normative physical characteristics and nonverbal behaviors contribute to perceptions of creepiness.
- Participants did not believe that most creepy people realize they
are creepy, nor did they believe that creepy people necessarily have bad
intentions. However, they also believed that creepy people could not
change.
- The most frequently mentioned creepy hobbies involved collecting
things, such as dolls, insects, or body parts such as teeth. Bones or
fingernails were considered especially creepy; the second most
frequently mentioned creepy hobby involved some variation of "watching,"
such as taking pictures of people, watching children, pornography, and even bird watching.
The results are consistent with the idea that creepiness is a
response to the ambiguity of threat. Non-normative non-verbal
and emotional behaviors, unusual physical characteristics and hobbies,
or suspect occupations set off our “creepiness detector." Men are
considered more likely to be creepy by males and females alike; women
are more likely to perceive sexual threat from creepy people.
We have not yet published our results, but we have presented at
several conferences. And I plan to expand my study from creepy people to
creepy places: We become uneasy, for example, in environments that are
dark and/or offer a lot of hiding places for potential predators and
also lack clear, unobstructed views of the landscape. These
environmental qualities have been called “prospect” and "refuge” by
British geographer Jay Appleton. Fear of
crime and
a pervasive sense of unease are experienced in environments with less
than optimal combinations of prospect and refuge. In creepy places as
with creepy people, I expect to find that it is not the clear presence
of danger that creeps us out, but rather the
uncertainty of whether danger is present or not.
