“When we are tired or preoccupied - what psychologists call 'resource-depleted' - we start to economise, to conserve those resources. Higher-order thinking is more expensive. So too is doubt, scepticism, arugment. 'Resource depletion specifically disables cognitive elaboration,' wrote Harvard psychologist Daniel Gillbert...Because it takes less brain power to believe than to doublt, we are, when tired or distracted, gullible. Because we are all biased, and biases are quick and effortless, exhaustion tends to make us prefer the information we know and are comfortable with. We are too tired to do the heavier lifting of examining new or contradictory information, so we fall back on our biases the opinions and the people we already trust”

“When we care about people, we care less about money, and when we care about money, we care less about people.”

“In treating people as less important than things, work becomes both demoralised and demoralising and we become blind to the moral content of our decisions...Money and wilfful blindness make us act in ways incompatible wiht what believe our ethics to be, and often even with our own self-interest...the problem with money isn't fundamentally about greed, although it can be comforting to think so. The problem with money is that we live in societies in which mutual support and co-operation is essential, but money erodes the relationships we need to lead productive, fulfilling and genuinely happy lives. When money becomes the dominant behavior, it doesn't cooperate with, or amplify, our relationships; it disengages us from them.”

“Money is just one of the forces that blind us to information and issues which we could pay attention to - but don't. It exacerbates and often rewards all the other drivers of willful blindness; our preference for the familiar, our love for individuals and for big ideas, a love of busyness and our dislike of conflict and change, the human instinct to obey and conform and our skill at displacing and diffusing responsibility. All of these operate and collaborate with varying intensities at different moments in our lives. The common denominator is that they all make us protect our sense of self-worth, reducing dissonance and conferring a sense of security, however illusory. In some ways, they all act like money; making us feel good at first, with consequences we don't see. We wouldn't be so blind if our blindness didn't deliver rewards; the benefit of comfort and ease.”

“The human tendency toward confirmatory thinking - all of us are bias to seek information that fits what we already believe.”

“Humans do not have enough mental capacity to do all the things that we think we can do. As attentional load increases, attentional capacity gradually diminishes.”

“When heuristics don’t yield the results we expect, you’d think we would eventually realize that something’s wrong. Even if we don’t locate the biases, we should be able to see the discrepancy between what we wanted and what we got, right? Well, not necessarily. As it turns out, we have biases that support our biases! If we’re partial to one option—perhaps because it’s more memorable, or framed to minimize loss, or seemingly consistent with a promising pattern—we tend to search for information that will justify choosing that option. On the one hand, it’s sensible to make choices that we can defend with data and a list of reasons. On the other hand, if we’re not careful, we’re likely to conduct an imbalanced analysis, falling prey to a cluster of errors collectively known as “confirmation biases.”
