Consider EVERYTHING but one must not forget to think critically…
Some recent modern examples were the 2000 computer disaster (Y2K) and the 2012 Mayan Calendar Predictions…consider them…think critical…and disregard what really doesn’t pass the test of critical thinking.
Most things that sound plausible and aren’t in fact plausible, are based on SOMEWHAT factual concerns and issues.
If you’re wrong…then you’re wrong. You’ll also be wrong if you consider EVERYTHING to be valid. Some of it just isn’t.
