In hindsight, that may have been the case, but I don't think that was the reason the decision was made not to fly. I do believe there was confidence that the forecast was being interpreted correctly. "It's wind shear...that's gotta be bad, so I'll sit this one out." Versus, "I am not sure what the WS code means to me, so I'll stay on the ground since I don't understand it." These are two different cases. Either way, a poor interpretation of the weather and forecasts can be fixed with some education and that's the point of my message. The other thing that occurs is that a pilot who does fly in this situation and is expecting it to be really nasty, but the air is glassy smooth...then they blame the forecast for being incorrect, when in fact, it's not a forecast for turbulence at all.
