"People tend to conform their factual beliefs to ones that are consistent with their cultural outlook, their world view," Braman says. The Cultural Cognition Project has conducted several experiments to back that up. Participants in these experiments are asked to describe their cultural beliefs. Some embrace new technology, authority and free enterprise. They are labeled the "individualistic" group. Others are suspicious of authority or of commerce and industry. Braman calls them "communitarians." In one experiment, Braman queried these subjects about something unfamiliar to them: nanotechnology — new research into tiny, molecule-sized objects that could lead to novel products. "These two groups start to polarize as soon as you start to describe some of the potential benefits and harms," Braman says. The individualists tended to like nanotechnology. The communitarians generally viewed it as dangerous. Both groups made their decisions based on the same information. "It doesn't matter whether you show them negative or positive information, they reject the information that is contrary to what they would like to believe, and they glom onto the positive information," Braman says.

"Basically the reason that people react in a close-minded way to information is that the implications of it threaten their values," says Dan Kahan, a law professor at Yale University and a member of The Cultural Cognition Project. Kahan says people test new information against their preexisting view of how the world should work. "If the implication, the outcome, can affirm your values, you think about it in a much more open-minded way," he says. And if the information doesn't, you tend to reject it. In another experiment, people read a United Nations study about the dangers of global warming. Then the researchers told the participants that the solution to global warming is to regulate industrial pollution. Many in the individualistic group then rejected the climate science. But when more nuclear power was offered as the solution, says Braman, "they said, you know, it turns out global warming is a serious problem."And for the communitarians, climate danger seemed less serious if the only solution was more nuclear power.

However, tax experts say that if you want to really annoy the IRS, you could do one of three things: Fail to file a return completely; loudly maintain that the tax code doesn’t apply to you; or cheat on employment tax filings for your workers. Stack appears to have done all three. And if the tone of his letter is any indication, he not only hit all of these IRS hot buttons, he hit them with a belligerent attitude that could have further exacerbated his tax woes. “The IRS is toughest on people who reject the whole concept and authority of the system, who are not accepting that we do have income tax laws that we are all subject to,” said Philip J. Holthouse, partner at the Santa Monica tax law and accounting firm of Holthouse, Carlin & Van Trigt. “If the anger expressed in this posting is consistent with how he interacted with the government representatives, it would not have enhanced their compassion.” Stack’s note refers to meeting with “a group” in the early 1980s who were holding “tax readings and discussions” that zeroed in on tax exemptions that make “the vulgar, corrupt Catholic Church so incredibly wealthy.” He said in the post that he then began to do “exactly what the ‘big boys’ were doing.” “We took a great deal of care to make it all visible, following all of the rules, exactly the way the law said it was to be done.” Since Stack wasn’t a church, this is like waving a red flag at a bull. The IRS apparently considered this foray into tax avoidance the real corruption. Stacks letter says: “That little lesson in patriotism cost me $40,000.” Incidentally, the notion that anyone (other than a legitimate charity) doesn’t need to pay income taxes is one that’s well familiar–and refuted–by not only the IRS but every legitimate tax preparer in the country. So-called tax protestors or “tax defiers” take bits and pieces of the law, string them together in incomprehensible ways to come up with arguments that they say exempt them from tax. They can sound convincing, so the IRS publishes a long list of “frivolous” tax arguments on its web site, explaining when and where each argument was refuted, in an effort to keep innocent taxpayers from drinking the tax protest KoolAid. But that wasn’t all. Stack also says in his letter that he drained a retirement account and didn’t pay tax on any of that money–didn’t even file a return. The penalties for not filing a tax return are roughly ten times worse than for not paying your taxes. That’s one of the reasons that accountants tell their clients to file returns, even when they don’t have the money to pay, said Holthouse. Finally, Stack rails about independent contractor rules. Experts said the only way this rant could make sense is if Stack started a company that employed other people, who he maintained were independent contractors rather than employees. If an employer maintains he’s hired only independent contractors, he doesn’t need to pay Social Security and Medicare taxes on their wages. But the IRS audits these claims carefully. When an employee is improperly classified as an independent contractor so that the employer can avoid these taxes, the IRS prosecutes aggressively because it considers it tantamount to stealing from workers Social Security and Medicare accounts. Notably, the IRS has a Taxpayer Advocate’s office that helps resolve disputes when taxpayers have a legitimate problem with the agency. People who can’t pay tax bills promptly; have a dispute over the validity of a deduction or think they’ve been improperly penalized are often given some slack. But these are not areas where you’re going to get a lot of sympathy.

Solar-powered drip irrigation enhances food security in the Sudano–Sahel documents a field research project which found that: "solar-powered drip irrigation significantly augments both household income and nutritional intake, particularly during the dry season, and is cost effective compared to alternative technologies" Over the decades, irrigation has been shown to greatly increase agricultural productivity. Drip irrigation is spreading rapidly in Africa, with significant benefits. "Drip irrigation delivers water (and fertilizer) directly to the roots of plants, thereby improving soil moisture conditions; in some studies, this has resulted in yield gains of up to 100%, water savings of up to 40–80%, and associated fertilizer, pesticide, and labor savings over conventional irrigation systems" The solar-powered systems, however, look to offer the potential for even better results. From the study on impacts of PVDI systems it was reported: "The women’s agricultural group members utilizing the PVDI systems became strong net producers in vegetables with extra income earned from sales, significantly increasing their purchases of staples, pulses, and protein during the dry season, and oil during the rainy season. Finally, survey respondents were asked how frequently they were unable to meet their household food needs. Based on the frequency and most recent incident, households were assigned a food insecurity score ranging from zero (no problems during the previous year) to one (perpetually unable to meet food needs). This score changed significantly for project beneficiaries, as they were 17% less likely to feel chronically food-insecure. In short, the PVDI systems had a remarkable effect on both year-round and seasonal food access."

No silver bullets. This is the simple premise of Diane Ravitch’s new book, “The Death and Life of the Great American School System,” which is being brought out this week by Basic Books. Written by one of our nation’s most respected scholars, it has been eagerly awaited. But it has also been, at least in some quarters, anticipated with a certain foreboding, because it was likely to debunk much of the conventional — and some not so conventional — wisdom surrounding education reform.

What of the once-great comprehensive high schools, institutions with history and in some cases a track record of success going back generations? As time moves on, it is fast becoming clear that the new small schools, many with inane themes (how about the School of Peace and Diversity?), can never substitute for a good neighborhood high school, which can become a center of communal life and pride. Ms. Ravitch’s report underscores the fact that the trick is to fix the neighborhood schools beset with problems, not destroy them.

It is not only the foundations that Ms. Ravitch blames for the current crisis: government has also failed in the attempt to reform the schools from above, lacking a clear perspective of how schools work on a day-to-day basis. Thus, the major federal initiative, No Child Left Behind, well intentioned as it may have been, ended up damaging the quality of education, not improving it. While the federal government declares schools as “failing” and prescribes sanctions for schools not meeting its goal of “annual yearly progress,” it is the states that are allowed to write and administer the tests. This has led to a culture of ever easier tests and more test preparation rather than real instruction. More ominously, it led to such scandals as the New York State Education Department lowering the “cut scores” that define the line between passing and failing. Ms. Ravitch suggests that the proper roles of the states and federal government have been reversed under NCLB. Maybe the standards for achievement should be set in Washington, which, after all, administers the National Assessment of Educational Progress , and the solutions found at the local level, using the accurate data provided by Washington. Instead of moving in a different direction from the failed NCLB model of the Bush Administration, the Obama administration has adopted and expanded on them.
