Otherwise, you'd have people not caring about being in a party that consistently takes 10mins to clear a raid when the average sets it at 5mins.
I experience a different happenstance, and that happenstance is, usually some individuals are parsing their own runs with random people in the hopes of posting an Orange or what have you, instead of focusing on clearing the content. This results in them taking risks to maximize personal DPS without communicating what they want to healers, or the party in the cases that it is the healers themselves doing this.

Most of the time, average times don't matter to anyone, only things like skipping potentially problematic mechanics. In general, it seems to be selfishness over consistency. It happens in statics too, but statics are generally aware of who their selfish players are, and they generally work around them, especially if they are exceptional.
