Finding the Real You

    Psychometric testing—personality testing—has been very popular nowadays as studies show their results to be three times more accurate in predicting your job performance. These tests are now included in almost all graduate recruitment (招聘) and are widely used in the selection of managers.

    The most popular of these personality tests is the Myers-Briggs Type Indicator (MBTI). It is based on the theory that we are born with a tendency to one personality type which stays more or less fixed throughout life. You answer 88 questions and are then given your “type”, such as Outgoing or Quiet, Feeling or Thinking.

    Critics of personality testing raise doubts about “social engineering”. Psychologist Dr. Colin Gill warns that the “popular” personality traits (特性) have their disadvantages. “People who are extremely open to new experiences can be butterflies, going from one idea to the next without mastering any of them.” However, the psychometric test is here to stay, which may be why a whole sub-industry on cheating personality tests has sprung up. “It's possible to cheat,” admits Gill, “but having to pretend to be the person you are at work will be tiring and unhappy and probably short-lived.”

    So can we change our personality? “Your basic personalities fixed by the time you're 21,”says Gill, “but it can be affected by motivation and intelligence. If you didn't have the personality type to be a doctor but desperately wanted to be one and were intelligent enough to master the skills, you could still go ahead. But trying to go too much against type for too long requires much energy and is actually to be suffered for long. I think it's why we're seeing this trend for downshifting—too many people trying to fit into a type that they aren't really suited for.”

    Our interest in personality now exists in every part of our lives. If you ask an expert for advice on anything, you'll probably be quizzed about your personality. But if personality tests have any value to us, perhaps it is to free us from the idea that all of us are full of potential, and remind us of what we are. As they say in one test when they ask for your age: pick the one you are, not the one you wish you were.

    Last night, on my way home I stopped because of being attracted by some hamburgers at a fast food restaurant. On my way in, a homeless man approached me and asked, “Do you have any bottles lying around?” I knew he would recycle them for a few cents, but I didn't have any, so I said no. And again he asked, “Can you spare some change (零钱)?” I smiled, and said no again. He was very respectful; he smiled back and said, “OK, thank you.” Even though he didn't have anything, he was still in good spirits. From the way he spoke I could tell he was smart.

    Then I bought one hamburger and enjoyed my meal, but in the back of my mind I wondered whether the homeless man was hungry. After I finished my meal I decided to order another one for him. At this point I didn't know if he was still around, but I tried anyway.

    At the counter I ordered a hamburger and also a hot chocolate, because it was cold outside, and I thought it would help warm him up. They delivered me the hot chocolate first and as I waited for my hamburger, I noticed the homeless man was standing right beside me. I looked at him and smiled, “This hot chocolate is for you.”He replied like a gentleman,“Thank you so much. That's very kind of you.”

    I always believe no matter how hard up (缺钱) I am, there are always those who are worse off than I. When you help someone, it's not always about money, it's about love. The love you give today, someone might forget tomorrow. It doesn't matter. Love anyway, because the greatest thing you can give is love.

    Most people looking for ways to quit smoking worry about weight gain, and with good reason. Smokers who quit tend to pack on an average of 5 pounds after they stop smoking cigarettes. A new study, published by the journal Science, explains why this happens.

    The new research explains that nicotine appears to combine with appetite-regulating neurons (调节食欲的神经元) in the brain, besides the receptors (感受器) that bring about addiction. These neurons help regulate how much food gets consumed, but under the influence of nicotine, they lose their self-control. This is why when smokers quit, they tend to eat more and gain weight.

    The researchers believe that their discovery will lead to the development of drugs that aim at nicotine receptors on brain cells that control appetite. In the future, weight gain may no longer be a reason for smokers to delay the decision to kick the habit, but that's no reason to wait. Nicotine-replacement treatment, while not for everyone, can help. Here are a few more ways to quit smoking and stay slim.

    Drink water. To improve metabolic (新陈代谢的) rates, make half of those glasses ice water. Juice can be too high in calories, something you'll want to keep an eye on your journey toward being a slimmer non-smoker. Plan your snacks. Healthy snacks help keep your metabolism working, so you continue to burn calories while stopping wild hunger pain, or fake hunger.

    Keep moving. Exercise kills two birds with one stone. It helps you burn calories and prevents you from eating when you're not truly hungry. It's also a feel-good stress reliever (缓解物). Focus on your fitness and how being healthy makes you feel. Make exercise a goal and think of quitting as your reward for being physically fit.

    Next month, I'm traveling to a remote area of Central Africa and my aim is to know enough Lingala — one of the local languages — to have a conversation. I wasn't sure how I was going to manage this — until I discovered a way to learn all the vocabulary I'm going to need. Thanks to Memrise, the app I'm using. It feels just like a game.

    "People often stop learning things because they feel they're not making progress or because it all feels like too much hard work," says Ed Cooke, one of the people who created Memrise. "We're trying to create a form of learning experience that is fun and is something you'd want to do instead of watching TV."

    Memrise gives you a few new words to learn and these are "seeds" which you plant in your "greenhouse". When you practice the words, you "water your plants". When the app believes that you have really remembered a word, it moves the word to your "garden". And if you forget to log on (登录)，the app sends you emails that remind you to "water your plants".

    The app uses two principles about learning. The first is that people remember things better when they link them to a picture in their mind. Memrise translates words into your own language, but it also encourages you to use "mems". For example, I memorized motele, the Lingala word for "engine", using a mem I created — I imagined an old engine in a motel (汽车旅馆) room.

    The second principle is that we need to stop after studying words and then repeat them again later, leaving time between study sessions. Memrise helps you with this, because it's the kind of app you only use for five or ten minutes a day.

    I've learnt hundreds of Lingala words with Memrise. I know this won't make me a fluent speaker, but I hope I'll be able to do more than just smile when I meet people in Congo. Now, I need to go and water my Vocabulary!

When I teach research methods, a major focus is peer review. As a process, peer review evaluates academic papers for their quality, integrity and impact on a field, largely shaping what scientists accept as "knowledge"- By instinct, any academic follows up a new idea with the question, "Was that peer reviewed?"

Although I believe in the importance of peer review and I help do peer reviews for several academic journals-I know how vulnerable the process can be. 

I had my first encounter with peer review during my first year as a Ph. D student. One day, my adviser handed me an essay and told me to have my -written review back to him in a week. But at the time, I certainly was not a "peer"--I was too new in my field. Manipulated data （不实的数据） or substandard methods could easily have gone undetected. Knowledge is not self-evident. Only experts would be able to notice them, and even then, experts do not always agree on what they notice. 

Let's say in my life I only see white swans. Maybe I write an essay, concluding that all swans are white. And a "peer" says, "Wait a minute, I've seen black swans. "I would have to refine my knowledge. 

The peer plays a key role evaluating observations with the overall goal of advancing knowledge. For example, if the above story were reversed, and peer reviewers who all believed that all swans were white came across the first study observing a black swan, the study would receive a lot of attention. 

So why was a first-year graduate student getting to stand in for an expert? Why would my review count the same as an expert's review? One answer: The process relies almost entirely on unpaid labor. 

Despite the fact that peers are professionals, peer review is not a profession. As a result, the same over-worked scholars often receive masses of the peer review requests. Besides the labor inequity, a small pool of experts can lead to a narrowed process of what is publishable or what counts as knowledge, directly threatening diversity of perspectives and scholars. Without a large enough reviewer pool, the process can easily fall victim to biases, arising from a small community recognizing each other's work and compromising conflicts of interest. 

Despite these challenges. I still tell my students that peer review offers the best method for evaluating studies aird advancing knowledge. As a process, peer review theoretically works. The question is whether the issues with peer review can be addressed by professionalizing the field.
