There are two schools of thought on this one.
1) Those who prefer dethatching say that by removing the old dead grass, it makes it easier for new seed to take hold and start growing to fill out the lawn.
2) Those who prefer core aeration say that you have thatch because nutrients and water
can't get down into your lawn to keep your current grass growing. If you dethatch and overseed, you won't take care of the proximate cause.
I plan to do a core aeration of my lawn in the fall then overseed it. Once water and fertilizer can get deep into the lawn and help the new grass develop good strong roots while strengthening the roots of the current lawn, new grass will grow and thicken the lawn.
That's just one amateur gardener's perspective.
