<h2>Natural vs Artificial; Old vs New</h2>
<p>This leads me to ask? Is the question of natural vs artificial in the same category as the prompt - “Is old considered inferior?” A lot of times people attribute natural to being superior and artificial to inferior. Although one can argue that ‘old is superior’ in some situations but for some reason and maybe psychologically, we tend to resist new technology and designs. We always lean towards the old way of doing things.</p>

<h2>Regulatory environment</h2>
<p>If we start focusing on Humanity Center Design, does this mean we need to start building out regulations that are ethical for design? How do you know what is ethically correct, when there are 8+ different ethical standards out there?</p>
<aside class="notes">
<p>Norman has long championed the idea that designers need to be more like engineers, with standards that qualify them. There are increasing numbers of certifications for designers, but Norman thinks we could go further.</p>
<p>Certainly, the notion of ethics is controversial and people may try to manipulate ethical standards for their own gain. For example, major corporations resist ethics regulations and often spend more money on publicity campaigns to promote an ethical image than on the actual struggle to maintain ethical standards. This is because, in the USA today, profit trumps all other considerations. Can anything stand in the way of profit as our main consideration in life?</p>

<p>About eight percent of Northern European males in your audience probably suffer from red-green color blindness, for example, and mobile apps exist specifically to help people identify colors.</p>
<p>This frame shows an example of a color blindness test from the Color blindness article on Wikipedia. If you are not color blind, you should see the number 74. If you are red-green color blind, you should see the number 21. If you have total color blindness, you should see no numbers. By the way, Wikipedia reports that several famous artists throughout history are thought to have been color blind, so color blindness should not preclude a career as an artist or designer.</p>
<p>One note on Wikipedia is that I refer to it a lot, in contrast to instructors who note that there is a lot of misinformation on Wikipedia and ask you to refrain from using it. I view Wikipedia as valuable but flawed, and I believe there is a skill you can develop with experience of using it and triangulating with other sources to overcome the misinformation problem. Wikipedia is often a good starting point for a search even for poorly researched articles. It just shouldn’t be the ending point.</p>

<h2>An example of Colorbrewer usage</h2>
<img data-src="fiColorbrewer.png" class="r-stretch"><aside class="notes">
<p>Colorbrewer is an idea and an application and a website and the basis for several tools, conceived by geography professor Cynthia Brewer. The main idea is that people have an easier time interpreting information represented by some colors than by others.</p>
<p>Brewer and her students have conducted countless experiments with colored maps, asking participants quantitative questions about information depicted by the maps. They’ve kept a careful record of how well participants answered questions using different color schemes, and developed a set of color palettes representing the most successful combinations.</p>
<p>The <a href="http://colorbrewer2.org">colorbrewer</a> website, shown in this frame, shows the control panel on the left and the result on the right. The user is asked to tell the number of data classes to be represented on the map. Then the user has to decide whether their data is sequential, diverging, or qualitative. Next, on the basis of these choices, a set of color schemes is presented to choose from. Further choices offered include whether the color scheme should be colorblind safe, print friendly, or photocopy safe. You get a depiction of the color scheme in the map on the right hand side, and a list of the colors in either hexadecimal, RGB, or CMYK format.</p>

<h2>You don’t notice the gorilla when counting</h2>
<img data-src="fiBasketballPassing.png" class="r-stretch"><aside class="notes">
<p>Inattention blindness is depicted in this frame. In this famous experiment, the participant is asked to watch two basketball teams, one wearing white and the other wearing black. The participant is asked to count the number of passes made by one of the teams, but not the passes made by the other team. After a few seconds, a person in a gorilla costume walks through the scene but the participant is so intent on the counting task as to not see the gorilla!</p>
<p>You can find many examples of similar experiments with similar results online by searching for inattention blindness or cognitive overload. One of my favorites is shown on Youtube where a researcher on the sidewalk asks a random person for help with a map. As soon as the random person starts looking at the map and trying to make sense of it, a pair of workmen holding a large mirror pass between the two. Unbeknownst to the random person, a confederate is hiding behind the mirror with the same map folded in the same orientation. The confederate replaces the researcher, who walks on behind the mirror. The confederate is of a different race and gender than the researcher, but the video evidence suggests that the random person does not know the difference. As a side note, there may be a serious ethical issue with this experiment because the random person is drawn into it without informed consent.</p>

<p>One interesting experiment reported in the book suggests that being watched by eyes in a picture can influence your behavior. The researchers found an office with a kitchen where people were supposed to put money in a box every time they took milk from the refrigerator. Over the box was a framed picture. The researchers manipulated the picture, changing it for a different one every week. The two kinds of subjects for the picture were flowers and eyes watching the viewer. As shown in Figure <span class="math inline">\(\ref{fiThinkingFastSlow2.jpg}\)</span>, people were more apt to put money in the box while they were being watched! Could this be conscious behavior?

<h2>Cost-benefit analysis and risk management</h2>

<h2>Values of Humanity vs Artificial Measures</h2>
<ul>
<li>Cost Benefit Analysis and Risk Management tend to favor more expensive buildings, businesses, and homes</li>
<li>Wealthy always win cost benefit analyses and risk mgt analyses</li>

<ul>
<li>Alternatives require subjective measures</li>
<li>Objective is “better” than subjective even though the things you most care about in the world are probably measured subjectively</li>
<li>One article said GDP was up, another said people were down … Why the discrepancy?</li>

<ul>

<li>Counts cost and waste as economic benefits</li>
<li>Summarizes economic status of a nation as a single number, hiding complexity: opaque, invisible, mysterious, secretive, confusing</li>
<li>Spending measured by GDP includes causing pollution and cleaning up pollution, as well as large police forces and repairing broken windows</li>
