We are surrounded, in our day to day lives by what Jacoby refers to as "junk thought": attempts by proponents of various theories, dogmas, and ideologies to convince us of their arguments by utilizing language that - on the surface at least - appears scientific or authoritative. These arguments all share one common feature: the reliance on the ignorance of the target audience. That is one aspect in which we excel as a nation. Members of American society (actually, many wealthy societies), as they rely more and more on electronic media for their information, seem to be embracing a culture of ignorance. If we were to look at what is presented to us with a critical eye, however, rather than taking what is offered us at face value, we would see much of it for what it is: junk.
The danger in this junk thought - from the rejection of climate change science to the unfounded belief that vaccinations cause autism - is that it is presented as fact. If accepted as fact, it has the power to block progress, or even to reverse progress we've already made. Worse yet, and as we have demonstrated in recent months, as America goes, so goes the world. If there is any greater argument against the "banking" concept of education, which we read about at the beginning of the semester, it is that if we are not taught how to think rather than what to think, then every one of us will fall victim to junk thought.
