You spend years gathering data, running experiments, peer-reviewing your findings, and finally publish your groundbreaking research. You present it to the world expecting people to embrace the evidence... only to watch them reject it because it doesn't match their preconceived notions or what their uncle posted on Facebook. The "spring washers don't work" is such a perfect example because it's a real engineering debate! Spring washers (those little split metal rings) were once thought to prevent bolts from loosening, but modern studies show they're basically useless for that purpose. Yet people still use them everywhere because "that's how we've always done it." It's like watching someone discover fire and then watching everyone else say "nah, I prefer rubbing sticks together." Scientists really do feel like they're presenting ancient scrolls of wisdom, only to have them yeeted back into the ocean when the data challenges established practices or beliefs. Evidence-based decision making? More like evidence-based disappointment!
