I wrote a master's paper on Herbert A. Simon's idea of satisficing, as opposed to optimizing. Maybe we don't seek the all-out BEST. Maybe there isn't really a single best except under special circumstances, measured in a given time and place. Who is the best batter? The best quarterback? It may be better to aim to have a good product that serves us well, to have a good batter and a good quarterback.
You may have heard the statement that 98% of statistics are made up on the spot. I just made up the 98%. I chose it. Truthfully, I doubt that fake or unfounded numbers are quite that common. I don't doubt that there are claims of numbers and of quality ("Ours is the best!") that have little or no evidence behind them. I also don't doubt that what's best in one setting may be "sub-optimal" (less than best) is another.
