Meet Joe Slack
My boyfriend does everything halfway, save for playing video games and smoking weed. He does sloppy work at his job, just the minimum to get by, and is always late turning things in. He's gotten away with this so far, maybe because he's charismatic and fun. In our relationship, he'll promise me one thing and do another, and he does sneaky-lazy things like using up my shampoo but leaving the empty bottle in the shower. He's highly intelligent and could be so much better than this. Is there a way to get him to change?
Sadly, few companies have the kind of position he'd be ideal for: Vice President of Watching Porn During Business Hours.
Novelist F. Scott Fitzgerald wrote that "action is character." The way somebody repeatedly behaves reflects the sort of person they are: for example, highly trustworthy or "better lock up the silverware — including the stainless steel!"
Psychologists boil down a person's typical way of behaving — along with the recurring thoughts and feelings that drive it — as personality traits (for instance, extraversion). Personality traits have a hefty genetic component — maybe even 50 percent — and tend to be pretty consistent over time and in different situations. (A barfighter is a barfighter is a barfighter.)
Like classic Jolly Ranchers, personality traits come in five core "flavors," which psychologists remember with the acronym OCEAN: Openness, Conscientiousness, Extroversion, Agreeableness, and Neuroticism (aka emotional stability). Each trait is actually a spectrum ranging from low to high (from very little of a trait to lots and lots of it).
Ethically elastic, lazy sociopotato behavior like your boyfriend's reflects low conscientiousness. A person high in conscientiousness is disciplined, dependable, and organized, with strong self-control, while someone low in conscientiousness is unreliable, undisciplined, and slothful, with poor impulse control and little concern for how their multislacking affects others. They can be wonderfully spontaneous and a lot of fun — that is, until they spontaneously pawn your dog to stake themselves into high-roller poker.
Being conscientious is one of the most reliable predictors of success — in any job from CEO to dog groomer to Etsy birdhouse magnate. It's natural to assume low conscientiousness is bad and high is good. But high conscientiousness has a number of downsides, such as buttcheek-clenching inflexibility, crippling perfectionism, and being about as spur-of-the-moment fun as a refrigerated corpse.
Additionally, evolutionary anthropologist Daniel Nettle observes that the benefits of high conscientiousness are "exaggerated" in the "artificial ecologies" of modern workplaces. "Few of our ancestors survived and reproduced by being able to stay in the same place for eight hours a day, quietly getting on with a series of pre-planned or repetitive tasks" like entering sales data into spreadsheets. For an ancestral hunter-gatherer, life was "a series of urgent improvisations" to manage surprising situations that constantly popped up. "It would really not be a good response, observing a passing herd of wildebeest, to say, 'Actually Wednesday is my honey-gathering day.'"
Interestingly, research by psychologist Joanna Moutafi and her colleagues finds a relationship between high intelligence and low conscientiousness, suggesting that being brainy allows for slackadaisical behavior. People who are very smart learn that they can goof off and do work at the last minute because they've got the mental juice to squeak by.
Can a brainy slothlete like your boyfriend change? Maybe. But the chances of this happening simply because you ask are probably slim. Change is more likely to come through getting hit hard by some catastrophic loss, like getting canned or dumped or driving while sloshed and mowing down the neighbors.
However, you could tell your boyfriend you think he's awesome in many ways, but you see him doing things halfway, and it makes every area of his life so much less than it could be. Paint a picture of how great things could be if he just put in a bit more effort. Assuming he doesn't shut you down, suggest an experiment. For two weeks, he could pick a couple of things to do really well every day: one at home (maybe making the bed like they do at a nice hotel) and another at work. During the two weeks, pump him up when he follows through, and afterward, ask him how it made him feel: about himself, his job prospects, and making you feel loved.
Going back to Fitzgerald's "action is character," if your boyfriend feels good enough to keep up and expand the changes, you might see that action also becomes character. We can choose who we are (probably more than most of us think) by repeatedly acting like the sort of person we want to be. Accordingly, some committed slackers do finally start climbing the corporate ladder; however, others prefer to keep napping underneath. ("My spirit animal is the sinkhole!")
