Missing stair

Missing stair is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Missing stair rather than just read about it. In short: The missing stair is a metaphor for a person within a social group or organization who many people know is untrustworthy or otherwise has to be "managed", but around whom the group chooses to work by discreetly warning newcomers of their behavior, rather than address the person and their behavior openly. The "missing stair" in the metaphor refers to a dangerous structural fault, such as a missing step in a staircase…

Key takeaways

  • Missing stair belongs to science; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.
  • Connect Missing stair to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of Missing stair from memory before moving on to harder problems.

Reference excerpt

The missing stair is a metaphor for a person within a social group or organization who many people know is untrustworthy or otherwise has to be "managed", but around whom the group chooses to work by discreetly warning newcomers of their behavior, rather than address the person and their behavior openly. The "missing stair" in the metaphor refers to a dangerous structural fault, such as a missing step in a staircase; a fault that people may become used to and quietly accepting of, that is not openly signposted or fixed, and that newcomers to a group or organization are warned about discreetly.

Origins

The phrase was coined by blogger Cliff Jerrison in a 2012 post on The Pervocracy, a blog about BDSM and kink. Describing a man in his social circle known to be a rapist, Pervocracy wrote:

People had gotten so used to working around this guy, to accommodating his "special requirements," that they didn't feel like there was an urgent problem in their community. They did eventually expel him, but it was after months of it being widely shared knowledge that he was a rapist. [...] I think there were some people in the community who were intentionally protecting him, but there were more who were de facto protecting him by treating him like a missing stair. Like something you're so used to working around, you never stop to ask "what if we actually fixed this?" Eventually you take it for granted that working around this guy is just a fact of life, and if he hurts someone, that's the fault of whoever didn't apply the workarounds correctly. Jerrison intended the term to apply beyond sexually predatory behavior, including, for example, underperforming colleagues who let others pick up their slack. While "missing stair" has most often been used in the context of sexual misconduct, it may describe a variety of uncomfortable social or professional circumstances.

Meaning The analogy of the missing stair makes it clear that the problem is the predator (the missing stair) and that the solution is stopping the predatory behavior (fixing the stair). An article about industry sexual harassment on comics news site ComicsAlliance posed the question: "Which one of these statements makes more sense to say: 'These people need to find more ways to stop people from harming them.' OR: 'These people should stop causing harm.' If you ever find yourself saying the former instead of the latter, take a moment and ask yourself why." In a 2014 post on the anti-rape blog Yes Means Yes, lawyer Thomas MacAulay Millar wrote that the missing stair analogy was consistent with his understanding of rapists' motivations and behaviors, based on research carried out by clinical psychologists David Lisak and Paul M. Miller, and by Stephanie K. McWhorter, a researcher with the U.S. Naval Health Research Center. Millar wrote that while a small number of rapists are "one-timers" who may be making a mistake or are confused about consent, the majority are repeat offenders, averaging six rapes each. "We need to spot the rapists," Millar wrote, "and we need to shut down the social structures that give them a license to operate. They don't accidentally end up in a room with a woman too drunk or high to consent or resist; they plan on getting there and that's where they end up."

Usage The analogy has been picked up and used in communities related to paganism, comics, punk, geek culture, and in Tavi Gevinson's Rookie, a magazine for teenage girls. It has been used by advice columnists, including Captain Awkward and Sam W. at Scarleteen. Geek culture site The Mary Sue referenced the concept in 2013, in a story celebrating science fiction writer John Scalzi's announcement that he would no longer attend science fiction conventions that did not have clear and prominent sexual harassment policies. In 2014, Feministe quoted science fiction editor Michi Trota describing James Frenkel, who was permanently banned from attending Wiscon after harassment complaints, as "someone who has been an industry missing stair for decades." In 2014, Yes Means Yes compared disgraced former broadcaster and pop musician Jian Ghomeshi to a missing stair, and urged the BDSM community to distance themselves from him. In 2015, the missing stair concept was invoked by The Guardian in its coverage of American astronomer Geoffrey Marcy's resignation from his professorship at UC Berkeley, following its finding that he had repeatedly violated the university's sexual harassment policy between 2001 and 2010. In 2015, after pornographic film actress Stoya accused her colleague and former boyfriend James Deen of rape, prompting similar allegations by a dozen other women, feminist site We Hunted the Mammoth wrote that James Deen seemed to be "a perfect example" of a missing stair. On NPR, in a review of the 2015 Jo Walton science fiction/fantasy novel The Just City, reviewer Amal El-Mohtar argued that Walton deliberately included missing stairs in her book, in an effort to reflect current discourse around the topic. In 2017, adult performer Jessica Drake gave an interview to Rolling Stone, and commented regarding the allegations surrounding colleague and fellow performer Ron Jeremy: "I have viewed [Ron Jeremy] as the missing stair in the adult community."

Worked examples

Example 1 — a first encounter with Missing stair

Start with the simplest possible case. Write down what Missing stair claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Missing stair before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Missing stair ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Missing stair

In research
Missing stair appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses Missing stair in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom
Missing stair is common in secondary-school and first-year university syllabi. It links to neighbouring topics Concepts in social philosophy, Deviance (sociology), Metaphors referring to places, so understanding it makes those chapters shorter.
In everyday life
Look for Missing stair outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
