Four out of Five Experts Agree — With Me!

The research team, led by Dan Kahan of Yale Law School, studied “a broadly representative sample” of 1,500 Americans in 2009. Through a series of questions, their cultural beliefs were measured on what can be called a left-right scale (although the researchers do not use the terms “liberal” and “conservative” in their paper). Those strongly holding egalitarian and communitarian outlooks were on one end of the spectrum, while those with hierarchical and individualistic views were on the other.

Participants were then presented with a series of statements and asked whether in their view most experts concurred with them. Three of the statements represented the consensus of scientific opinion: “Global temperatures are increasing,” “Human activity is causing global warming,” and “Radioactive wastes from nuclear power can be safely disposed of in deep underground storage facilities.”

Finally, the participants were introduced to a fictional expert on one of those subjects, who either agreed or disagreed with their position. After reviewing the researcher’s credentials and reading a bit of their writing, each participant rated the degree to which they found the expert knowledgeable and trustworthy.

New research finds we trust experts who agree with our own opinions, suggesting that subjective feelings override scientific information.

A clear consensus of opinion emerges within the scientific community on an important issue, such as climate change. But the public, and its elected leaders, remains unconvinced and unreceptive to well-founded warnings.

With this phenomenon growing frustratingly familiar, researchers can be forgiven if they begin to feel like Rodney Dangerfields in lab coats. From their perspective, they don’t get no respect.

Newly published research suggests that’s not entirely true: Americans do believe and trust researchers. But we focus our attention on those experts whose ideas conform with our preconceived notions. The others tend to get discounted or ignored.

“Scientific opinion fails to quiet societal disputes on such issues (as climate change) not because members of the public are unwilling to defer to experts, but because culturally diverse persons tend to form opposing perceptions of what experts believe,” a team of scholars writes in the Journal of Risk Research. “Individuals systematically overestimate the degree of scientific support for positions they are culturally predisposed to accept.” Leer más “Four out of Five Experts Agree — With Me!”

How to Become an Eco Web Designer

Whether you believe in global warming or otherwise, the earth does still have limited resources. With an ever increasing population this means that we should try and reduce our consumption of fuel and wastage whenever possible. While I’m not going to start a hippy campaign and say that we should all go live in a world without computers (that would drive me to the point of insanity) I think that as web professionals, there are small things we can do to pass on the savings to our customers.

This article aims to highlight some of those potential energy and resource saving tweaks that we can make to ensure that if our visitors wish to reduce the amount of resources they expend, the process will be as painless and unobtrusive as possible. While this list is certainly not extensive, hopefully it may give you the opportunity to think about the process you use to build a website and how to best meet the ecological needs of your visitors as they are of an ever increasing level of importance.

Save Energy

Figure 1: Recognising ways to save energy will make you an eco designer.

Note: Everything listed has some scientific credibility behind the theory, but the amount of savings that can be made depend on various factors. My advice is that if doing small things can help visitors reduce their electricity bills or resource costs without incurring extra ourselves, it’s worth the effort!

Blackle is The New White

While this item has a lot of controversy surrounding it, there is some clear merit associated with the practice therefore it’s worth breaking apart the facts from the fiction. A few years ago a site called Blackle appeared and made a name for itself due to its simple idea that by using a black background, you could reduce the amount of energy expended by your display. The theory behind this was that it requires more energy to illuminate a white pixel than a black (non active) one, sounds easy right?

Figure 2: Blackle conceptualises a method to help CRT displays reduce their energy consumption.

Well the truth is that the claims by promoters of the theory itself based on a scientific study were rather exaggerated. You see, with the advancement of technologies and the progression from CRT displays (which a real difference can be measured) to LCD’s (which require near enough the same amount of energy to produce black as white), much of the idea behind such a noble campaign has been debunked. So why is this item included in the list? For one reason, backwards compatibility!

As web professionals we are used to the fact that people may be browsing our sites using clunky old pieces of technology, from elderly browsers to a machine that would have been in existence longer than your children. It’s still a fact today that many people still regularly make use of CRT displays as they visit websites. Therefore it may be worth the consideration of giving your users an alternative stylesheet which they can pick based on black to pass on potential energy savings to those devices.

When the temperature of our planet increases, it means that our planet is hot and ill! The rise in your body temperature is called fever, when the same happen to earth atmosphere and ocean it is called Global Warming. So today we have collected 30 incredible artworks related to global warming. Comments are really appreciated.
