Chocolate Cake Resistance

It is now a well-established proposition that both self-control and cognitive effort are forms of mental work. Several psychological studies have shown that people who are simultaneously challenged by a demanding cognitive task and by a temptation are more likely to yield to the temptation.

Imagine that you are asked to retain a list of seven digits for a minute or two. You are told that remembering the digits is your top priority. While your attention is focused on the digits, you are offered a choice between two desserts: a sinful chocolate cake and a virtuous fruit salad. The evidence suggests that you would be more likely to select the tempting chocolate cake when your mind is loaded with digits.

People who are cognitively busy are also more likely to make selfish choices, use sexist language, and make superficial judgments in social situations. A few drinks have the same effect, as does a sleepless night. The self-control of morning people is impaired at night; the reverse is true of night people. Too much concern about how well one is doing in a task sometimes disrupts performance by loading short-term memory with pointless anxious thoughts.

The conclusion is straightforward: self-control requires attention and effort.

Rich and Poor Cheat for Different Reasons

In certain circumstances, it's the poor who are more likely to cheat. The difference is that the rich do wrong to help themselves, while the poor do wrong to help others. In several experiments reported in an upcoming issue of the Journal of Personality and Social Psychology… the studies suggest a straightforward sequence: Money leads to the perception that one is higher in the social hierarchy, which in turn leads to a sense of power, which in turn leads to a greater willingness to cheat for selfish reasons.

People with less money (and therefore less power), however, are more communal. They need to rely on each other to get by, and as a result, research shows, they’re more compassionate and empathically accurate. Breaking rules is always risky, but social cohesion is paramount — so you do what it takes to help those around you.

The researchers think their findings could lead to some easy practical applications. If you’re speaking to higher-class individuals, you might want to appeal to their selfishness and warn that cheating will ultimately backfire. But when talking to those with fewer resources, you might be better off noting that their actions could harm those around them.

Alone

What can you ever really know of other people's souls—of their temptations, their opportunities, their struggles? One soul in the whole creation you do know: and it is the only one whose fate is placed in your hands. If there is a God, you are, in a sense, alone with Him.
