I'm not sure what to make of this

Here:

In general, 67 percent of people prefer PCs over Macs. But among those who have acted dumber than they actually are to improve their social standing, 79 percent prefer PCs.

• Mac users have an exaggerated view of their social standing?
• Mac users are more arrogant than PC users?
• Mac users' social circles are less obsequious to idiots?
• Some sort of Dunning-Kruger thing I'm not quite grasping?
• Liars feel empathy for Redmond?
