One of the questions I get asked most often after a mentalism performance is some version of “was that psychology?” It’s a specific question asked with a particular tone — not accusatory, not skeptical exactly, but searching. They want to categorize what they saw. They want a folder to file it in.
For a long time, I didn’t fully understand why this question was so common, or what it told me about the audience’s experience. Now I understand it quite precisely, because it’s a direct product of a principle Henning Nelms articulates in Magic and Showmanship that he calls mock explanations.
The audience is always looking for a theory. When they can’t find one on their own, they become more susceptible to adopting one that’s offered. And if you offer them a plausible false theory — one that sounds like it explains what they saw, that’s internally consistent, that they can accept and repeat to others — they’ll adopt it. And once they’ve adopted a theory, they stop looking for a better one.
“Was that psychology?” is the question of someone who has provisionally adopted the theory that what they saw was psychological technique — something learnable, something scientific, something explicable if you knew more about human behavior. That theory is false. But it’s a comfortable false theory, and it protects what actually happened far more effectively than silence would.
The Theory-Seeking Behavior
The starting point for understanding mock explanations is recognizing how strongly human beings resist unexplained experience. We don’t just dislike not having answers — we actively generate answers. The mind prefers a wrong theory to no theory. This is well-documented in cognitive psychology: confabulation, the construction of plausible narratives to explain experiences we don’t understand, is a normal cognitive process, not a pathology.
In the context of a magic performance, this means the audience is not just passively watching and then failing to understand. They’re actively generating theories. After every effect, there’s a micro-period of hypothesis formation. They’re reaching for explanations. And the theory that gets adopted first tends to stick — because once you have a theory, the cognitive discomfort of inexplicability is resolved, and the motivation to keep searching disappears.
Nelms’ insight is that you can deliberately feed this process. Rather than leaving the audience to generate theories on their own — which might sometimes produce accurate hypotheses — you provide a theory that’s plausible, compelling, and wrong.
What Mock Explanations Look Like
A mock explanation is usually built into the presentation rather than offered as explicit commentary. You don’t say “this works because of psychology.” You present the effect within a framework that implicitly suggests that’s the basis.
When you frame an effect as being about reading behavioral signals, the audience’s implicit theory is that you read them somehow. When you frame it as being about statistical probability, their implicit theory is that you made a calculation. When you frame it as being about unconscious pattern recognition, their implicit theory is that you perceived something they didn’t know they were communicating.
Each of these is a mock explanation: plausible, internally consistent, and false. And each protects the real method by pre-occupying the hypothesis space. The audience has a theory. The theory feels good enough. The search stops.
Themed Presentations as Structural Mock Explanations
I think of my themed presentations as mock explanations at the structural level. The theme isn’t just decorative context — it’s the implicit framework within which the audience will try to understand what they’re seeing.
When I present something within a framework that emphasizes my interest in human psychology and decision-making — which is genuine, as a consultant and as someone who’s spent years studying the research on attention and perception — the audience naturally categorizes what they see as being in the domain of psychology. Their reconstruction attempts operate within that category.
What they’re less likely to consider are explanations from outside that category. The theme has created a conceptual container, and the audience’s analysis stays inside it. Anything that’s actually happening outside that container is protected by the boundary of the frame.
This is why theme is not decoration. It’s architecture. The theme builds the conceptual space within which the audience will try to understand the performance. Design the theme deliberately, and you design the limits of their reconstruction process.
The Self-Sustaining Nature of Adopted Theories
One underappreciated feature of mock explanations is that once adopted, they’re self-sustaining. When the audience tells others about what they saw, they’ll naturally include the theory: “He was reading our body language” or “It was some kind of psychological thing.” The theory becomes the story of the performance, which means subsequent audience members arrive already primed to see the performance through that theoretical lens.
This is a significant form of protection. Not only is the mock explanation working on the live audience — it’s working on anyone they talk to afterward, who will watch a future performance with the false theory already in place. The mock explanation propagates.
This has implications for how you want the audience to talk about what they’ve seen. The story they’ll tell is at least partly in your control — the framing you provide becomes their language for describing the experience. And that language carries the false theory.
The Legitimate Basis Problem
A complication: mock explanations are most effective when they have a legitimate partial truth to them. If the false theory has absolutely no connection to reality, sophisticated audiences will eventually notice that it fails to fully account for what they saw. The theory will feel like a rationalization rather than an explanation.
The best mock explanations are theories that are right about the domain even when they’re wrong about the specific mechanism. Saying that an effect involves psychology is not entirely false if you’re genuinely interested in and knowledgeable about psychology and it genuinely informs how you present your work. The theory is correct in spirit and wrong in specifics.
This partial truth is what gives the theory its sticking power. The audience doesn’t feel manipulated by a false theory that has genuine content behind it. They feel like they’ve understood something real, which they have — they just haven’t understood the specific mechanism.
An Honest Reflection
I want to be clear about something. Using mock explanations is a sophisticated form of misdirection, and I don’t take that lightly. In a performance context — where the audience has come specifically to be fooled, to have their reconstruction process frustrated, to experience the pleasurable confusion of a well-constructed effect — this is legitimate craft.
But I’m aware that I’m also a professional speaker and consultant who talks about psychology, cognition, and decision-making in contexts that are not performance. In those contexts, I’m careful to be exactly accurate about what I know and what I’m claiming. The mock explanation is a performance tool. Outside performance, the standard is different.
What the mock explanation principle teaches me, beyond its specific application, is how strongly audiences want to categorize and explain their experience. That desire is legitimate and worth respecting. The best magic — and the best keynote experiences — leave the audience with something to think about even when the false theory has eventually dissolved and they realize they still don’t know how it worked.
The theory is a gift of temporary resolution. The real experience is the astonishment underneath it.
