Could 3D printing or other custom-manufacturing methods create physical artifacts to help people think better? For example:

• Bayesian Belief Bangles — rotating ring bracelets to track likelihoods ...
• Decider Devices — recommender-rosaries to fuse factors and suggest optimal choices ...
• Statistical Sliders — minute mechanisms to accumulate and update uncertainties based on data ...
• Category Theoretic Cogwheels — conceptual constructors to combine concepts and conjure metaphors ...
• Mental Model Musical Machinery — flute-like fluidic causal flow simulators on which to play System Dynamic archetypes ...

... hmmmmm!
