Improvements to Scoring Algorithm

• Fix algorithm for 3-level arguments (post->note->subnote): estimate $P(A|C)$ using tallies for A given considered C.
• Better heuristic for top note: $informedVotes × relativeEntropy$
• Adjustment for Informed Vote Selection Bias
• Adjustment for Entrenchment Bias: Users’ informed votes influenced by whether they voted on post before voting on note
• Implement/Improve support formula (use $P(note|subnote)$ to inform prior for $P(post|subnote)$:
  • deal with probabilities below 0 or about 1
  • improvements based on notes in 2024-03-05-support-formula-derivation.md
• Reversion Constant: Better prior for informed probability by assuming informed probability tends to regress to the mean.
• Thomson Sampling
• Integrate MCMC sampling instead of using the Bayesian Averaging approximation
• Better solution for duplicates using the “great aunt” rule
