Staffing professionals don't need to be told this but according to new research from the London School of Economics,  it's not what you know, it's who you know:

New ideas and technologies are not the product of a few far-sighted geniuses but arise through societies and social networks acting as collective brains, says new research from LSE and Harvard University.
The paper, published in the journal Philosophical Transactions of the Royal Society B, argues that, over evolutionary time, individuals who mimicked other successful individuals  eating the foods they ate or hunting with the tools they used, for example became successful themselves without necessarily understanding why. Over time, innovations emerged through the mixing of ideas, serendipity and incremental improvement. These accumulated over generations and were similarly passed on as cultural knowledge leading to the complex world we live in today.
