Unfortunately I think this is a great thread lol. It's unfortunate because our world has made this type of thread necessary. It's a good thread for newcomers and veterans alike in my opinion. S+F
Critical thinking is thinking that questions assumptions. It is a way of deciding whether a claim is always true, sometimes true, partly true, or false.
Critical thinking has been described as "reasonable reflective thinking focused on deciding what to believe or do." It has also been described as "thinking about thinking." It has been described in more detail as "the intellectually disciplined process of actively and skillfully conceptualizing, applying, analyzing, synthesizing, and/or evaluating information gathered from, or generated by, observation, experience, reflection, reasoning, or communication, as a guide to belief and action".
Confirmation bias refers to a type of selective thinking whereby one tends to notice and to look for what confirms one's beliefs, and to ignore, not look for, or undervalue the relevance of what contradicts one's beliefs
Confirmation bias is seeing the world through a filter, thinking selectively.
