Give each message six language scores
We score clarity, guidance, evidence, reassurance, choice, and cost language. You can review and change every score.
A synthetic message experiment
Test three message ideas against a made-up audience. Then rebuild that audience 50 times to see whether the ranking holds.
This is a thought experiment with invented inputs. It does not predict how real people will respond.
The whole test
We score clarity, guidance, evidence, reassurance, choice, and cost language. You can review and change every score.
Each fictional person values the six scores differently. A message earns a higher fit score when its language matches those invented needs.
Monte Carlo repeats the whole comparison while the people and selected assumptions change. We count how often each message ranks first.
Set up the test
Three message ideas
Each comparison tests three different message strategies. Every line comes with a matching, reviewable score profile so you can see exactly what the model is comparing.
Made-up audience
The demo invents three audience types and a starting mix. Each type values different parts of a message. The names, shares, traits, and preferences below are assumptions—not measured people or a market estimate.
03 / Run the comparison
One world creates a fictional audience and scores all three messages once. Monte Carlo repeats that full step. The final result combines every world—not just the first one.
The three message lines · the three audience types · the six score definitions · your replay code
The fictional people · the mix of audience types · each message score within its shown range · how much each score matters
Result across every world
Fit score is a 0–100 model score. It is not a response rate. Worlds won is the share of repeated fictional worlds where that message ranked first.
Why repeat the test?
One made-up world gives one answer. Repeating the same test with controlled changes shows whether that answer is stable or fragile.
Each dot is one whole fictional world. Its color shows which of the three messages ranked first in that world.
Stanislaw Ulam considers estimating the chance of winning by playing repeatedly instead of calculating every possible game.
John von Neumann develops the approach for early computers and difficult neutron problems.
Nicholas Metropolis and Ulam publish the method. Its casino-inspired name makes chance part of its identity.
Monte Carlo is used in physics, engineering, finance, measurement, and other complex systems.

In plain English
What it does not do: predict a response rate, represent a real population, or replace research with people.
