I am not an advocate for the 250 hour pilots in the airline flightdecks, but there have been many studies that show that statistically, the lower time pilots may be less likley to have an incident due to being overly cautious. The same studies point out that the middle time pilots are the most incident prone due to complacency and being to comfortable in the cockpit.

Again, I am not an advocate for wet ticket new hires, but I don't think that the lions share of the blame can be placed on the inexperienced guy in the right seat. Oh, and for the one that brought up Tenerife...it was the right seat and back seat drivers that told the captain (25000 hr) to stop...he went anyway.
