According to Webster: it means to be "made dull, apathetic, or cynical by experience or by surfeit"
In going though graduate school I feel like too many people graduate a bit on the jaded side. Worse yet, that being jaded is something to joke about AND is just a part of developing as a scientist. We all know that science works about 1% of the time....maybe...and its 100% alright to get bummed out and unmotivated during the lowest of the low's. It is also understandable to vent to others in order to keep plodding along. But I do NOT understand why it is socially accepted to be a Jaded student...to be completely negative about the research he/she does, to avoid showing up to journal clubs/seminars, or to never participate in scientific discussions. What does being burnt out do for you in becoming the best you can be?? How does it help your science, your field, or your coworkers??
I really only notice these attributes in young scientists, i.e. graduate students and post-docs. Does this mean that the Jaded ones eventually give-up, get use to it, change their prospectives, or do they hide that inner Jaded color as they progress?? Or maybe it's just that grad students/postdocs can't seem to see the light at the end of the tunnel until they get there??
Anywhichway, science is exciting and challenging...please don't let it beat you down. Here, I'll give ya a hug to keep those spirits up....*Hug*
