A crowdsourced list of sci/tech/biz words nerds use to signal that they’re smart

These are perfectly good words in their native sci/tech/biz context, but risk being pretentious when used u̶t̶i̶l̶i̶z̶e̶d̶ in day-to-day conversation

Note: Many of these terms are more precise than their common-use matches. That’s okay. The whole point of this list is that increased precision does not compensate for decreased accessibility to a non-technical audience.

Please suggest others in the comments!

From Statistics

  • “Priors” instead of assumptions; (if you want to get really nerdy, you can say “posteriors” instead of conclusions). (“All political discussion on Twitter is just people confirming their priors”)
  • N” instead of many (“It’s really an N-dimensional problem”)
  • Dimensions/Dimensional” instead of sides/sided (see above)
  • Over-index” instead of bias (“Perhaps you’re over-indexing on your Bay Area experience”)
  • Non-zero possibility” instead of not impossible (“There’s a non-zero possibility that Trump could win again”)
  • Tail risks” instead of rare risks (aka Black Swans) (“We need to start thinking about the tail risks of climate change”)
  • Causal structure” instead of underlying reason (“There must be some causal structure behind why this happened”)

From Mathematics

  • Orthogonal” instead of unrelated (“My political views are orthogonal to this conversation about you finishing your salad, young lady”)
  • Tangential” instead of minor or distractingly irrelevant. (“That’s a tangential topic. Let’s stay on track..”)

  • “Exponential growth” instead of fast growth. As it happens, most growth people describe as exponential is actually polynomial although in fairness nerds are less guilty of that than most.
  • “QED” instead of “proven” or “shown”, but usually “there we go” is sufficient.
  • “First Order”, “Second Order”, “Third Order” instead of obvious, less obvious etc
  • Tradespace” instead of market or range (“What’s my favorite dried bean variety? I haven’t explored the tradespace enough to properly answer the question.”)
  • Surface Area” instead of scope or likelihood (“If you want to increase your surface area for serendipity, it is fine to have a longer tail of small allocations in your portfolio.”) (extra points for the long tail reference, which I have humbly omitted from this list)

  • “Quantum leap” In physics, it’s the smallest possible leap (such as of an electron from one energy level to another). It’s now misused to mean any large step

From Computer Science

  • High-dimensional” instead of complicated (“That’s a high-dimensional problem”)

  • Nash equilibrium” instead of stable mediocrity (“I’m against cancel culture because it causes society to glide into Nash equilibrium”)
  • Game theory” (v) instead of analyze. Most occurrences are along the lines of “if you game theory it, you’d find that” but don’t actually use any game theory
  • Marginal utility” instead of advantage (“The marginal utility of getting up in the morning is really falling in quarantine”)
  • Steep learning curve” instead of hard to learn (“This software has a steep learning curve.”) [Note: in machine learning within computer science, a steep learning curve actually indicates a model learns quickly, not slowly.]

From Finance:

  • Call Option/Put Option” instead of “bet on/bet against”
  • “Short/Long” ditto
  • “NPV” (net present value) instead of simply “value” (guy in boardroom: “The NPV of our people’s happiness…”)

  • Surface” (verb, as in submarine rising to the surface) instead of reveal ( “When we refactored the app, our cohort made a non-linear, quantum leap when we determined that surfacing the stakeholder parameters was necessary”)
  • “Ballistic” instead of angry as in “he went ballistic”. Referring to the incoming path of an ICBM. The reason this is used to mean “angry” is that when the ICBM ends its boost phase and enters its ballistic phase, that means that its ultimate target and outcome (boom) is already determined.
  • “Non-linear” instead of crazy, as in “he went non-linear”. Although this can refer to any curve other than a straight line, the common parlance refers to chaotic or exponential behavior
  • “Ground zero” from nuclear weapons, the point on the ground directly underneath an air blast. Misused to mean the the center of any effect, so that has become the conventional meaning now
  • “Broken Arrow” something that is extremely important or valuable that is lost, damaged beyond repair, or accidentally used. The original meaning was a nuclear weapon that is no longer under control, such as after an bomber crash.
  • “Defcon” acronym for “defense readiness condition”, followed by a whole number value between 5 and 1 with 1 being the most severe (IE: war) and 5 being normal. Most people get this backwards, thinking Defcon 5 is the worst.
  • “Attack Surface” instead of vulnerabilities. Now used in computer security to describe the many ways a hacker could penetrate a system
