Knowledge = Justified true belief, only when there is a throughline between all three elements such that the belief is because of the justification and is also true by virtue of the justification (solves the Gettier problem).
Justification = Epistemological Synthesism
Combine the virtues of different epistemological methodologies in a harmonious way as measured in terms of pragmatism - the ability to practically achieve successful results.
Epistemological Methodologies -
[Thesis] Deduction:
Use logic to combine statements in a mathematical way, such that knowledge can be obtained by necessary inference.
[Problem] Infinite Regress:
No deductions can be justified since there is no way to excape the need for unjustified axioms.
[Antithesis] Induction:
Appeal to probability and pattern recognition. 100% certainty is no longer required for knowledge. Relative knowledge - follow the highest probability explanation.
[Problem] Echo Chamber: Pattern recognition is very vulnerable to biased data.
[Synthesis] Abduction:
Combine the virtues of both deduction and induction such that you develop systems of epistemology (science) where the inductive observations are tested against deductive predictions to generate abductive conclusions, which form the foundation for an iteration of tests, creating an ecosystem of scientifically proven conclusions that form the foundation for more conclusions, such that none of the higher conclusions could be true without the lower conclusions also being true, creating an ever increasing system of certainty.
Psychological Abduction -
1. Identify the relevant logical chains of analysis for a given problem. [Deduction]
2. Recognize the pattern for when psychological deduction goes wrong (cognitive biases). [Induction]
3. Identify the logical chains your biases prevented you from seeing.[Deduction]
4. Gather information and evidence to see if it supports deducted conclusions. [Induction]
5. Recognize the pattern for when psychological induction goes wrong (selection bias). [Induction]
6. Gather information and evidence your biases prevented you from seeing. [Induction]
7. Land on the conclusion that makes that has the greatest probability of being right after incorporating both deduction and induction. [Abduction]
Social Abduction -
1. Identify the relevant sources of information for a given problem. [Deduction]
2. Identify the relevant authorities for a given problem. [Deduction]
3. Identify the logical chains relevant to a given problem (apply psychological abduction) [Deduction]
4. Recognize the pattern for when social epistemology goes wrong (polarization) [Induction]
5. Map out a probabilistic landscape to identify how much credence should be applied to each source, authority, system, or institution. [Induction]
5. Adjust credence based on biases each source would have for this specific problem. [Induction]
6. Aggregate all of the conclusions from each source, weighted by credence, to see where the net conclusion resides. Operate based on this net conclusion as the most reliable truth perspective. [Abduction]
