the unexamined thought is not worth thinking. billions of neurons following the least path of resistance. this means not everything works logically. the skills of logic and critical thinking are skills learned to balance out our emotions. and it takes practice. our memories are flawed, we take mental short cuts, and use (heuristics) mental patterns to following lines of thought.
how to compensate for our flawed mental cognition? Use systematic doubt; skepticism. Question everything you think you know. Basing beliefs on actual evidence. Are our conclusions reliable. A positive set of methods for examining reality. find the conclusions that are actually true. even science can turn pseudo. science is just a methodology to find what is true. sometimes, even the method itself is flawed.
What does it mean to actually know something. natural effects have natural causes. magical thinking does not work in a scientific environment. sometimes delusion can take over. inventing new realities or getting swept up in the beliefs of others. each of at this point seems to be one neuron in a collective. grouping and cohesion takes place at this point. like beliefs sticking with like believers. viral claims with a smidgen of truth can cause further confusion for the whole. false claims run rampant across the board.
investing emotion into a conclusion can cause one to twist facts and logic to suit an argument. Fact twisting to suit a given theory is done on a massive scale especially in the media. It invests in a 'scientific process to spread with the speed of electrons. Capturing 'credulous ideas and making them 'real'.
Influencers are marketing claims using persuasive speech to sell anything. Pseudo scientific claims are presented with grandiose ethos (experts) to give it weight. Compelling anecdotes go a long way in convincing any claim.
