A Ray of Hope For Americans and Scientific Literacy?

An anonymous reader with a snippet from Politico: "A finding in a study on the relationship between science literacy and political ideology surprised the Yale professor behind it: Tea party members know more science than non-tea partiers. Yale law professor Dan Kahan posted on his blog this week that he analyzed the responses of more than 2,000 American adults recruited for another study and found that, on average, people who leaned liberal were more science literate than those who leaned conservative. However, those who identified as part of the tea party movement were actually better versed in science than those who didn't, Kahan found. The findings met the conventional threshold of statistical significance, the professor said. Kahan wrote that not only did the findings surprise him, they embarrassed him. 'I've got to confess, though, I found this result surprising. As I pushed the button to run the analysis on my computer, I fully expected I'd be shown a modest negative correlation between identifying with the Tea Party and science comprehension,' Kahan wrote. 'But then again, I don't know a single person who identifies with the tea party,' he continued.'" More at the Independent Journal Review.

      You are almost right. The association with republicans leans from the fact that most of the tea party objections to the parties line up with the facade the republicans would put forward to get elected but forget about once in office. This was highlighted enormously with the bank bailouts, the GM bailouts, and the slush fund created under the guise of the stimulus in which the tea party movement more or less was created.

      In short, it was easier to hijack the republican party then to create a new party and complain that they don't get any respect like the libertarians and the greens party do. (note, that isn't a jolt on the libertarians or the greens, it is just an explanation of what was happening). This is what Obama is so pissed at, it is what McCain the maverick who lost against Obama was pissed at, and what the talking heads in the MMS echoed but failed to grasp.

      Sorry, but that's backward There is no way an "independent" party could "hijack" the enormous Republican party. The very idea is laughable. If they could have, there would have been no need for a third party at all. They could have just joined the Republicans and then reformed the party.

      One of the biggest reasons the libertarian and Green Parties get glossed over is that about 80% of their platforms are functionally identical or compatible to existing platforms of other parties. The problem for them is that the differences that do remain are showstoppers for them to be in those other platforms. The tea party movement realized that infiltrating one of those parties would allow changes like when the Christian Coalition took over the republicans at one point in time.

      The Republicans realized that the Tea Party (which, again, contained a significant number of former liberals) was actually trying to do what the Republicans SAID they were doing for decades, but not actually doing. This could have been devastating to the Republican party. So the Republican donned the masks of the Tea Party and pretended to be them. Successfully. And some of them are even halfway serious about it.

      That might be more believable if the Tea Party had not challenged republicans who held safe seats in government during the primaries just to lose the general election to political adversaries. What you are claiming would require the republicans to actually defeat themselves in an attempt to make themselves win under a false pretense. That's a little like a bank robber asking the cops to drive the get away car at his next heist.

      But make no mistake: this isn't the original Tea Party, even though some people have hung on. You will find no liberals there. You will probably find a lot of rhetoric about smaller government and lower taxes, but little real action.

      I think the recent government shut down proves you wrong on this. It was ineffective action but if you paid attention to the contents of Ted Cruze's speeches or the speeches of the Tea Party members who were behind it, you would understand that they did it specifically because the people asked them too do something.

      Just watch cruze's concession speech before the vote to end the shutdown and pay attention to what is being said before injecting your ideological opinions of the content.

      So you suggest that the republican party put on masks and pretended to be tea part members for some sort of gain. What type of gain have they received? what gain has the republicans received when it only divided the party showing the difference between the establishment and the tea party conservatives?

      Just no. First, the Greens are primarily a one-issue party. And second, while there are a few vague similarities between Libertarian values and the Republican platform, they are not even remotely the same. Especially when you consider that even when it comes to those similarities, the Republicans over the last few decades have been almost all talk and no walk. 80% is way, WAY off. If you are measuring actions, rather than words, try 10%.

      Not that I blame you personally. The Libertarian party is widely misunderstood, in part precisely because of misinformation from both the Democrats and Republicans. The Democrats, in particular, have frequently characterized Libertarians as being "far right", when nothing could be further from the truth. I mean, it's not even close. The Republicans, on the other hand, simply try to marginalize the Libertarians, because the Libertarians really mean what the Republicans only pretend, when it comes to "smaller government". (But again, that's only a part of the Libertarian platform.)

      You are arguing against yourself, and and making MY argument for me. Tea Partiers running against Republicans? Then how could Republicans BE Tea Partiers? This is actually part of my own argument. The Republicans saw the writing on the wall. They saw they were getting stiff opposition so they leaned in the direction the wind was blowing. But even those Tea Party principles they claim to have adopted, they adopted in weakened form. And they only did so because they were being challenged by the Tea Party.

      "I think the recent government shut down proves you wrong on this. It was ineffective action but if you paid attention to the contents of Ted Cruze's speeches or the speeches of the Tea Party members who were behind it, you would understand that they did it specifically because the people asked them too do something."

      No shit. I repeat: they saw the writing on the wall, and saw that the American public was highly supportive of the Tea Party. So they do those things. There is no conflict or contradiction there with what I was saying. Example: Ron Paul ran on the Republican ticket, yet few people would mistake him for anything but a Libertarian (although he does hold a few typical Republican values that conflict with Libertarian values). On the other hand, I don't think anybody would mistake Ted Cruz for anything but a Republican.

"We can't do this things! These things weren't intended by the founding fathers! They wrote the constitution specifically as they did as a guidepost for this country!"

The Constitution says nothing about protecting the skies, yet sane and reasonable people agree that it probably implies that would be ok, even though the founding fathers had never seen an airplane. The Constitutional also says nothing for or against social security, and in fact a later amendment permits it. We, as a country, have decided that the Constitution allows for social security as well. Yet to a tea partier, the air force is totally ok 100% implied by the constitution (even though it says nothing specifically about an air force) yet social security is not (even though the Constitution also says nothing about permitting an air force.)
