Well, according to the Scientific American, it's a little of both — and the way you perceive your own status updates definitely matters. Journalist Melanie Tannenbaum delves into decades of research on the ways that stating your goals publicly can alter your outcome.
Tannenbaum states that over 80 years of research has consistently found that "sharing your goal-pursuit intentions may actually make you less likely to pursue those goals." Wait, but why?
