View source for Mandela Effect Mechanism Theories

'''Mandela Effect Mechanism Theories''' is the [[The Cosmic Codex|Cosmic Codex]] umbrella over candidate explanatory mechanisms for the [[Mandela Effect Interpretations|Mandela-effect]] phenomenon-class. The umbrella collects mechanism-class candidates spanning mainstream-memory-research baseline to cluster-extension proposals; cluster discipline distinguishes phenomenon-categorisation (see [[Mandela Effect Categories]]) from mechanism-theorisation.

== Mechanism-Class Inventory ==

=== Mainstream-baseline class: Memory-research mechanisms ===
* '''Confabulation.''' Construction of false-memory through gap-filling, schema-driven inference, and post-event suggestion. See [[Mandela Effect Confabulation Hypothesis]] (this batch). Loftus 1974+ misinformation-effect research; Schacter ''Seven Sins of Memory'' 1999.
* '''Collective false-memory.''' Population-scale convergence on shared-false-memory through cultural diffusion, mass-media exposure, and social-reinforcement.
* '''Schema-driven misremembering.''' Memory-content shifted to fit cognitive-schema expectations (e.g., "Berenstein" matches familiar "-stein" name pattern more strongly than "Berenstain").

=== Cluster-extension class: Reality-substrate mechanisms ===
* '''[[Quantum-Branch Theory of Mandela Effect]] (this batch).''' Cluster-extension proposal: reported memory-divergence reflects branch-crossing across many-worlds-quantum-mechanics-style branches. Speculative-extension of Everett-Wheeler-DeWitt MWI framework.
* '''[[Consciousness-Substrate Theory of Mandela Effect]] (this batch).''' Cluster-extension proposal: reported memory-divergence reflects consciousness-substrate-mediated shifts in collective remembered-reality.
* '''[[Simulation-Glitch Theory of Mandela Effect]] (this batch).''' Cluster-extension proposal: reported memory-divergence reflects substrate-glitch in computational-reality-substrate (sim-hypothesis tradition).
* '''[[Timeline Manipulation]] (K1a) coupling.''' Cluster framing of subset-instances as deliberate-timeline-manipulation residue.

== Mechanism-Discrimination Discipline ==
The umbrella enforces cluster discipline:

* '''Mechanism-class falsifier-distinctness.''' Each mechanism-class is in-principle distinguishable by pre-registered prediction.
* '''Mainstream-baseline parsimony.''' Mainstream memory-research baseline explains most reported instances; cluster-extension claims require differential prediction.
* '''Differential-prediction examples.'''
** Confabulation predicts: no cross-individual-clustering of specific-memory beyond cultural-exposure baseline.
** Quantum-branch predicts: cross-individual-clustering of specific-memory exceeding cultural-exposure baseline.
** Consciousness-substrate predicts: cluster-pattern correlation with mass-coherence-event timing.
** Simulation-glitch predicts: discontinuous-cluster timing with no cultural-exposure correlate.

== Mainstream-Cluster Boundary ==
Cluster honesty position:

* '''Mainstream-class accounts for most instances.''' Confabulation + schema-driven misremembering + collective-false-memory account for most reported Mandela-effect instances under mainstream-research baseline.
* '''Cluster-extension-class operates on residual.''' Cluster-extension proposals operate on residual after mainstream-baseline accounting.
* '''Operationalisation gap.''' Pre-registered cross-individual-clustering studies are sparse; cluster discipline preserves humility regarding residual size.

== Quality-of-Engagement Discriminators ==
* '''Mechanism-discrimination discipline.''' Real and cluster-required.
* '''Mainstream-baseline parsimony.''' Cluster honesty: mainstream-class explains most instances.
* '''Differential-prediction pre-registration.''' Sparse in current literature; cluster discipline preserves humility.
