Sometimes the things they don't care about are also very deliberate. Google is perhaps the champion of causing harm by not caring about things. This is sometimes ascribed as being caused by their "engineering-centric culture", but I fail to see how engineering excellence can mesh with the real world experience of using their products. A broken clock is still broken even if all its gears are beautiful.
More to the point, I really wonder how exposure to the social sciences may help fix any of this.
