What is the difference between "synergistic" and "synergetic"? I believe they both speak of the cooperation of multiple things to produce an output, but how do they differ?
Synergistic is older and is still used scientifically in many fields. It usually means that there is a proven result that is more than the sum of its parts. I would use this term if there are corroborating results. Synergetic is newer and is most often used in coaching for productivity in work groups. It usually implies the intent and determination to produce better outcomes working in synergy with others, regardless of success.
