  • 1 in 6 chance, so not really. I think lots of the CBO projections during the healthcare debate assumed tax rates would revert to their pre-2003 levels.
  • story behind popular job hunting book "And, over the past three decades, Bolles's preferred method has remained remarkably consistent: Sending out résumés doesn't work. Neither does answering ads. Employment agencies? No way. What does work is figuring out what you like to do and what you do well -- and then finding a place that needs people like you. Contact organizations that you're interested in, even if they don't have known vacancies. (Bolles actually coined the now commonplace term "informational interview.") Pester friends and family members for leads. Once you get in the door of the employer of your dreams, show how you can solve its problems."
  • But even after controlling for nearly all imaginable variables — socioeconomic status, level of physical activity, number of close friends, quality of social support and so on — the researchers (a six-member team led by psychologist Charles Holahan of the University of Texas at Austin) found that over a 20-year period, mortality rates were highest for those who were not current drinkers, regardless of whether they used to be alcoholics, second highest for heavy drinkers and lowest for moderate drinkers.
  • an army chaplain in afghanistan has an atheist assistant, good article. "The chaplain was struck both by RP2 Chute's command of the Book of Revelation, and his refusal to take it seriously. "He's familiar with the Christian doctrine, but he chooses not to believe it," says the chaplain, a slender-faced, soft-spoken man with a fringe of gray in his black hair. "That's what I find puzzling."

Groupon’s purchase form leads to mistakes

Groupon’s got a great business model: Subscribers get one offer every morning in their inbox from a local restaurant or business, and a time period to redeem that offer. They have tons of revenue. This morning I purchased my first Groupon. Even though I’m a pretty advanced computer user, I failed their purchase process and had to enter in my credit card data twice, as well as make two purchases. Let’s break down why it happened.

The offer was for Mr. Cecil’s California Ribs. I emailed a friend and she agreed it looked awesome, so I clicked on the link to make the purchase. Here’s their purchase page, which every user receives, unless they’ve previously logged into Groupon and set cookies to remember their login and password.

Note I’ve tried to buy two Groupons at the top of the form. I start entering in my personal information, password and credit card info. What I actually need to do is login first, like every customer that gets the Groupon emails.

After I’ve gotten out my credit card and punched in the information, I click “Complete My Order.” But I’m told by Groupon that my email address is already registered (of course, I subscribe to the email) and that I need to sign in first.

So I go back to the sign up form and click the light green “Sign In” button, which I’ve completely ignored up to this point. With the purchase information right there in front of me, why should I bother signing in?

Now that I’ve signed in, all of my information’s gone and I need to enter it all in again. I enter all my credit card and billing information again, and then get told “Congratulations! You’ve bought 1 Groupon for Cecil’s Ribs!” but of course I wanted to order two – Groupon reset the quantity while I was logging in.

Now I have to click on the deal again and click “Buy Groupon” to get one more. This time Groupon’s saved my credit card info, so I don’t have to enter it again. However, it’s generally not good practice to take people’s credit card information without their consent.

Finally I have my two Groupons. I’ve had to enter in my data twice and I’ve had to make two separate purchases. All in all, this is pretty bad usability for a well-known company, and I hope they fix it soon. They need to filter users with accounts from users without accounts, through a two-stage purchase screen, or email link magic, or allow everyone to make a purchase without using an account.

And now checking the site for the third time, I notice that you can only use one Groupon per table. All in all, a frustrating customer experience.

  • Three forces trying to pull the Internet apart: Governments want more access to browsing history, email messages.

  • I wouldn’t have recognized him on the street and I didn’t know his name, but I knew him, or at least knew his body, and knew this odd habit of his. To put it in social-media terms, it was as if @weirdneighbor were tweeting, “I like playing piano in the nude. Whatever.” Because of the slant of the sun and the size of my windows, I don’t think he could see me, so our relationship, as it were, was less like Facebook, where the exchange is mutual, and more like Twitter: in other words, I was “following” him, but he wasn’t following me.

  • n both books we observed that payroll and wins in baseball do not have a strong correlation. Specifically, a team’s payroll only explains about 20% of a team’s wins. This means that it takes more than dollars to win in baseball. And this means that simply taking money from the rich teams and giving it to the poor teams is not going to transform baseball’s lower classes into winners. The Pirates appear to be agreeing with this observation. Rather than spend all the revenue sharing money – which may or may not lead to many more wins – the Pirates have decided to just keep part of this money as profits.

  • Libertarians are an increasingly vocal ideological group in U.S. politics, yet they are understudied compared to liberals and conservatives. Much of what is known about libertarians is based on the writing of libertarian intellectuals and political leaders, rather than surveying libertarians in the general population. Across three studies, 15 measures, and a large web-based sample (N = 152,239), we sought to understand the morality of selfdescribed libertarians. We found that, compared to liberals and conservatives, libertarians show 1) stronger endorsement of individual liberty as their foremost guiding principle and correspondingly weaker endorsement of other moral principles, 2) a relatively cerebral as opposed to emotional intellectual style, and 3) lower interdependence and social relatedness. Our findings add to a growing recognition of the role of psychological predispositions in the organization of political attitudes.
  • excellent, will blog soon: "Most academic efforts to understand morality and ideology come from theorists who constrain the moral domain to issues of harm and fairness. For such theorists, conservative beliefs are puzzles requiring non-moral explanations. In contrast, we present the "five foundations theory of intuitive ethics," which broadens the moral domain to match the anthropological literature on morality. We extend the theory by integrating it with a review of the sociological constructs of community, authority, and sacredness, as formulated by Emile Durkheim and others. We present data supporting the theory, which also shows that liberals may have a special difficulty in understanding the morality of conservatives. We suggest that what liberals see as a non-moral motivation for system justification may be better described as a moral motivation to protect society, groups, and the structures and constraints that are often (though not always) beneficial for individuals."
  • The conservative conception of American identity is so selective and so specific that it tends to suggest to its adherents that many (maybe even most!) Americans aren’t real Americans, or are Americans who betray real American ideals.
  • devastating palin takedown. too bad the audience we need to persuade doesn't read vanity fair After starting her new career as a national figure, Palin disengaged from the community. When in Wasilla, she rarely leaves the house. At her favorite coffee shop, Mocha Moose, Palin has been seen only once in the past three months. On those occasions when she goes to Church on the Rock, she usually arrives late, leaves early, and sits in the back. For runs to Target, she waits until it’s almost closing time. She has never darkened the doorway of Wasilla’s one independent bookstore, Pandemonium Booksellers, which took part in her Going Rogue book signing at the Curtis D. Menard Memorial Sports Center. Sarah’s mother, Sally Heath, is a charter member of the Valley Republican Women’s Club, which sells a batch of Palin-family recipes for $5, but Palin has not been to any of their meetings since resigning as governor.

  • Promotional video for luxury clothing company in the US. Great example of how to show, not tell, quality - show the tools, the care, the attention to detail, instead of just showing great suits
  • This article explores the dilemma of choosing talent using NBA data from 1987 to 2003. We find there is much uncertainty in selecting talent. If superstars are found, they are usually identified early. However, more false positives exist than correct decisions with high draft picks. Our results suggest the dilemma of choosing talent is not so much a winner's curse but more like a purchase of a lottery ticket. Most times you lose, but, if you are going to win, you must buy a ticket.

Great Design: Amazon’s sign in form

Companies have a problem on their sign in page: they need new users to register, and they need returning users to log in. Usually they have two separate forms, or one group gets short shrift. Jakob Nielsen pointed out Amazon's design in his latest Useit column, and the more I've looked at it the better it looks. I'm surprised more sites haven't copied this design. Both new and returning users have to enter in their email address. New users will not be able to enter in their password, so they find the radio button that says "I'm a new user" and Amazon's sped up the process by collecting their email address already. Returning users (the large majority) enter in their password and get started. Awesome.

  • In a hiring climate in which companies find talented workers by seeing how they already perform, the RethinkDB founders turned to sites like Github.com and stackoverflow.com, where programmers collaborate and work on special projects. "You can see the code being written and how technically accurate they are," said Glukhovsky, who inhabits a world where 95 percent of coders can't complete basic computer-science tasks. Now, a few months from releasing their first product, RethinkDB is up to six people, a mix of full-timers and interns, both senior and junior.

  • The prize firms are after: talented people, to be sure, but also the ability to tell clients, "We can put together a team for your company that is entirely made up of Ivy League graduates." Apparently this is enormously appealing to companies, which makes sense, given that law firms and especially consulting firms are often used as a kind of responsibility deferral system, allowing managers to fall back on some variation on, Yes, technically I approved this consequential decision that didn't actually work out for the company, but as you can see we hired the most prestigious consulting firm in America -- a whole room full of Harvard graduates! -- who affirmed that this was the best option.
  • Morgan Stanley’s report estimates that the ratio of current U.S. public debt to realistically realizable tax revenues is 3.58 to 1, which is the highest by a large margin of the countries in the report’s list; only Greece comes close (3.12 to 1). But America has certain advantages, such as a younger population and a more rapid rate of economic growth, and as a result its ratio of net worth to GDP is in the middle of Morgan Stanley’s list of countries—but it is strongly negative, as are the ratios of all the countries in the list (Italy, surprisingly, being at the top, and Greece, unsurprisingly, at the bottom). According to Morgan Stanley’s calculation (which obviously is merely suggestive, as the report emphasizes, because of the uncertainty of the future), America’s net worth is negative, and this negative net worth is eight times larger than our GDP. This means that the net present value of the government’s liabilities, minus assets, is approximately $120 trillion.

Fall 2010 Semester Goals

This semester's going to be the toughest semester I've had in terms of demands on my time. My goal this semester is just to show up, which Woody Allen says is "90% of life." If I can be reliable and turn in assignments when I'm supposed to, show up to parties when I'm supposed to, and meet application deadlines, that would be outstanding. Of course there's a lot of work that goes into that. I also have a body language related goal, to stop touching my face, stop looking around, and to keep my shoulders back. I also want to visit at least ten of Jonathan Gold's top 99 LA restaurants.
