to be open minded.
an open mind is a system, not a disposition. plans come from ideas, ideas come from explanations, and explanations stay good only inside a habitat that takes in new ones continually, filters them for signal and source, carries their context, refutes the bad and integrates the rest. build the habitat and good ideas become the default.

intake
new and varied explanations are processed continually. stories, books, podcasts and experience all carry them, and the medium matters far less than the substance. when information refuses to fit your world view, the default reaction is curiosity, not defensiveness.
signal
every channel holds a high signal-to-noise ratio. consuming without implementing gives no feedback from reality, so you overestimate what you know. keep the channels that feed your current problems and your highest goals, and cut the rest.
sources
explanations come from reliable sources. early in a subject you have no foundation to refute a bad explanation, so it takes root and its provider starts to look infallible. if the source lacks the output of their own advice, or profits from your belief, examine harder.
context
context travels with the explanation. context is the set of connections that tells a new explanation where to sit among your existing ones. name exactly which belief you are trying to change, or the listener assumes you are attacking all of them and shuts off completely.
integration
bad explanations are refuted, good ones integrated. refute the evidence, or refute its connection to the conclusion; nothing else counts. then remember you are not your beliefs: treat them as servants, and dismiss them when they stop serving you.
