(The other team is Houston. Missouri is #12.)
It's definitely objective because it's the output of a computer program. You can argue they're bad, sure, but they are definitely not the product of a personal bias in favor of the Big Ten. My computer rankings are mostly just for fun, I don't think they are the best algorithm or anything but I would put them against the eye test for handicapping any day.
But it's not like I'm an outlier here; as shown in my table above, Iowa is #8 Torvik, #5 Kenpom, #6 Massey, #6 Sagarin. Missouri is #20, #29, #15, and #32 in those rankings respectively. The theory behind these efficiency metrics is sound; the reason WHY the human rankings are so often so wrong is because people are blinded by raw W/L records like you are here. FYI Wichita State sucks; they are basically equivalent to Michigan State / Northwestern and here you are giving credit to Missouri for beating them because they ran up an 11-4 record playing noone.
(The reason why my rankings have Iowa lower and Missouri much higher than the other computers is that my system, being just for fun, gives a much larger bonus for simply winning games than any of the other systems do.)
