Picking what looks like the mid-point between extremes (centrism) means your view is shaped by whoever gets to define the spectrum of possible positions and it's "extremes" This is the definition of ideological capture.

I know of only 1 effective way to avoid it; refusing to commit to a hard position on any issue. At least without carefully investigating the available facts (historical, scientific, etc), and weighing up the logic of the arguments from all sides (there are always more than 2).
