Scientists have no obligation to look at the data or take it seriously. Scientists don't have skin in the game. They are totally immune to the consequences of their work. If thousands die because a scientist made an error in his research, nothing will happen to the scientist. At most, he'll have to publish a retraction, say "errors were made", say that this is how science progresses, maybe throw a joke in between. He might even end with an award. Compare with the engineer. If the plane crashes or the bridge collapses, the engineer will be immediately arrested, charged with homicide, sued out of the gains from his life's work, humiliated, and prevented from working as an engineer again.
