critical thinking and Machiavellianism are orthogonal. if you read the comments i am responding to, you'd see that those comments are the ones which are making the assumption that critical thinkers are non-Machiavellian, which is just as inane as the idea that critical thinking should be Machiavellian in nature. perhaps the problem is that for most people it is more emotionally satisfying to believe themselves as non-Machiavellian critical thinkers, thus confusing the two as related somehow.

consider two fundamental properties of critical thinking: asking the right questions, and objectivity. in a large organization that was defined (not by me) as having politics and power-playing as the main priority, then the person who thinks they are "getting things done" as long as those "things" do not involve icky political managerial dynamics ("selling my soul"), never thinking to question their own personal biases of "just because i like to put my head down and work on shipping product, is that the right thing to get done?", would seem to in fact not be engaging in critical thinking at all.

again, my reply is responding to (not supporting) the nonsensical proposition that critical thinkers (as ill-defined by other commentors) are more effective than Machiavellian actors, even as they are supposedly marginalized (aka rendered ineffective) within large organizations.

i can understand why that line of thinking is confusing, because it is.
