Quite easily, the BOD in many situations are there for dealing with problems, issues, and corporate governance only. The appointees are usually from a chosen market segment or profession to allot their expertise to the board.
I can unequivocally state that the board I report to, has little to no concept nor intimate knowledge of what we do. Like most boards, when I present quarterlies or year end, they just want the ROI to continue to grow every year.
SPECULATION ALERT
Its entirely possible that SI asked to see data or empirical proof and was told no.
