“Success begins with belief and ends with doubt.”—Larina Kase

    I remember reading through a book and the author was writing about being a reverse paranoid. In that particular section he mentions how he has a belief that the world he's living in is out to give him everything he absolutely wants and desires.

    There are times when I think to myself，“Wow，the world is out to get me and make me miserable.” Then I thought，why can't I believe that the world is out to make me a better conversationalist. Then I started adapting to the belief of the reverse paranoia.

    When I started talking to people，I truly believed that I was the most interesting person in the room. I believed that everything I said added value to the conversation. I believed that people stayed behind and chatted with me because they found me charismatic.

    As a matter of fact, for about five months I wrote down on my bathroom mirror the following affirmation：“People love me and respect me. It is a privilege to talk to me. People find me interesting and charming and always want to get to know me better！”

    I would say the affirmation after I brushed my teeth. And I would continue to say it until I felt completely great about myself. There were days that I just wouldn't feel like saying it，because it would feel like a lie to me. But that's the trouble，like the quote says，success ends when there's doubt. And that's why I continued until I had no doubt in my mind.

    Then strange things happened，I noticed that people did find me more interesting，and that I gained more confidence in talking with people. I was more assertive(坚定自信的) at work. I was able to control politics and gossip at work to minimal levels，and became a much better manager，and developed better customer relations to the point that sales were up by 20% compared to the year before，on my best month sales were up by 39%，and this was a year that a recession was happening.

                                                                     The Diet Zone: A Dangerous Place

    Diet Coke, diet Pepsi, diet pills, no-fat diet, vegetable diet… We are surrounded by the word “diet” everywhere we look and listen. We have so easily been attracted by the promise and potential of diet products that we have stopped thinking about what diet products are doing to us. We are paying for products that harm us psychologically and physically.

    Diet products significantly weaken us psychologically. On one level, we are not allowing our brain to admit that our weight problems lie not in actually losing the weight, but in controlling the consumption of fatty, high-calorie, unhealthy foods. Diet products allow us to jump over the thinking stage and go straight for the scale(秤)instead. All we have to do is to swallow or recognize the word “diet” in food labels.

    On another level, diet products have greater psychological effects. Every time we have a zero-calorie drink, we are telling ourselves without our awareness that we don't have to work to get results. Diet products make people believe that gain comes without pain, and that life can be without resistance and struggle.

    The danger of diet products lies not only in the psychological effects they have on us, but also in the physical harm that they cause. Diet foods can indirectly harm our bodies because consuming them instead of healthy foods means we are preventing our bodies from having basic nutrients. Diet foods and diet pills contain zero calorie only because the diet industry has created chemicals to produce these wonder products. Diet products may not be nutritional, and the chemicals that go into diet products are potentially dangerous.

    Now that we are aware of the effects that diet products have on us, it is time to seriously think about buying them. Losing weight lies in the power of minds, not in the power of chemicals. Once we realize this, we will be much better able to resist diet products, and therefore prevent the psychological and physical harm that comes from using them.

    GOING TO UNIVERSITY is supposed to be a mind-broadening experience. That statement is probably made in comparison to training for work straight after school, which might not be so encouraging. But is it actually true? Jessika Golle of the University of Tübingen, in Germany, thought she would try to find out. Her result, however, is not quite what might be expected. As she reports in Psychological Science this week, she found that those who have been to university do indeed seem to leave with broader and more inquiring minds than those who have spent their immediate post-school years in vocational (职业的) training for work. However, it was not the case that university broadened minds. Rather, work seemed to narrow them.

    Dr. Golle came to this conclusion after she and a team of colleagues studied the early careers of 2,095 German youngsters. The team used two standardized tests to assess their volunteers. One was of personality traits, including openness, conscientiousness（认真）and so on. The other was of attitudes, such as realistic, investigative and enterprising. They administered both tests twice—once towards the end of each volunteer's time at school, and then again six years later. Of the original group, 382 were on the intermediate track, from which there was a choice between the academic and vocational routes, and it was on these that the researchers focused. University beckoned for 212 of them. The remaining 170 chose vocational training and a job.

    When it came to the second round of tests, Dr. Golle found that the personalities of those who had gone to university had not changed significantly. Those who had undergone vocational training and then got jobs were not that much changed in personality, either—except in one crucial respect. They had become more conscientious.

    That sounds like a good thing, certainly compared with the common public image of undergraduates as a bunch of lazybones. But changes in attitude that the researchers recorded were rather worrying. In the university group, again, none were detectable. But those who had chosen the vocational route showed marked drops in interest in tasks that are investigative and enterprising in nature. And that might restrict their choice of careers.

    Some investigative and enterprising jobs, such as scientific research, are, indeed beyond the degreeless. But many, particularly in Germany, with its tradition of vocational training, are not. The researchers mention, for example, computer programmers and finance-sector workers as careers requiring these traits. If Dr. Golle is correct, and changes in attitude brought about by the very training Germany prides itself on are narrowing people's choices, that is indeed a matter worthy of serious consideration.

    There is a popular belief among parents that schools are no longer interested in spelling. No school I have ever taught in has ever ignored spelling or considered it unimportant as a basic skill. There are, however, different ideas about how to teach it, or how much priority (优先) it must be given over general language development and writing ability. The problem is how to encourage a child to express himself freely and confidently in writing without holding him back with the complexities (复杂性) of spelling. That's why teachers often encourage the early use of dictionaries and pay attention to content (内容) rather than spelling.

    If spelling becomes the only focus of his teacher's interest, clearly a bright child will be likely to "play safe". He will tend to write only words within his spelling range, choosing to avoid adventurous language.

    I was once shocked to read on the bottom of a piece of writing about a personal experience. "This work is terrible! There are far too many spelling mistakes and your writing is terrible." It may have been a sharp comment on the pupil's spelling in writing, but it was also a sad sign that the teacher had failed to read the composition, which contained some beautiful expressions of the child's deep feelings. The teacher was not wrong to draw attention to the mistakes, but if his priorities had centered on the child's ideas, an expression of his disappointment with the spelling would have given the pupil more encouragement to seek improvement.

 Imagine this. You need an image of a balloon for a work presentation and turn to an AI text- to- image generator, like Midjourney or DALL-E, to create a suitable image. You enter the prompt(提示词)" red balloon against a blue sky" but the generator returns an image of an egg instead.

What's going on? The generator you' re using may have been" poisoned". What does this mean?

Text- to- image generators work by being trained on large databasets that include millions or billions of images. Some of the generators have been trained by indiscriminately (任意地) scraping online images, many of which may be under copyright. This has led to many copyright infringement(侵害) cases where artists have accused big tech companies of stealing and profiting from their work.

 This is also where the idea of" poison" comes in. Researchers who want to empower individual artists have recently created a tool named" Nightshade" to fight back against unauthorised image scraping. The tool works by slightly changing an image's pixels(像素) in a way that confuses the computer vision system but leaves the image unchanged to a human's eyes. If an organization then scrapes one of these images to train a future AI model, its data pool becomes" poisoned". This can result in mistaken learning, which makes the generator return unintended results. As in our earlier example, a balloon might become an egg.

 The higher the number of" poisoned" images in the training data, the greater the impact. Because of how generative AI works, the damage from" poisoned" images also affects related prompt keywords. For example, if a" poisoned" image of a Picasso work is used in training data, prompt results for masterpieces from other artists can also be affected.

 Possibly, tools like Nightshade can be abused by some users to intentionally upload" poisoned" images in order to confuse AI generators. But the Nightshade's developer hopes the tool will make big tech companies more respectful of copyright. It does challenge a common belief among computer scientists that data found online can be used for any purpose they see fit.

 Human rights activists, for example, have been concerned for some time about the indiscriminate use of machine vision in wider society. This concern is particularly serious concerning facial recognition. There is a clear connect ion between facial recognition cases and data poisoning, as both relate to larger questions around technological governance. It may be better to see data poisoning as an innovative(创新的) solution to the denial of some fundamental human rights.
