They aren't talking about innovation but productivity. The OP asked "what bits of fundamental knowledge are productivity multipliers" this should hold true at whatever percentile of a field you chose, top 1%, 10% etc. However, it should be noted that the top 1% of innovators in a given field often do not understand the impact of their innovation on a multi-disciplinary or business context.
