How Pictures Skew Our Judgment 141

An article at Ars summarizes a study into how simply seeing pictures can alter what we believe, even if the pictures don't provide any information about the topic at hand (abstract). Researchers asked true-or-false questions to a group of test subjects about whether a minor celebrity was still alive. When they provided a picture of the celebrity, more people evaluated the statement as 'true' than when no picture was provided. The researchers then switched the question, asking whether it was true or false that the celebrity was dead. Again, the subjects shown a picture were more likely to respond with 'true.' Experiments also showed this phenomenon wasn't limited to questions about people, but general knowledge as well. "The authors spend a bit of time discussing why this sort of truth bias might arise. In cases where we have rich information—a photo or detailed description of something—it's easier to pull additional information out of our memory. So, even if a photo doesn't tell us much about whether the person is alive, it does make it easier to retrieve relevant information on them—if they're wearing a suit in the photo, we might reason they're a political or financial figure, etc. When the information flows that readily, we're more likely to conclude that we're familiar with the question that's being posed, and will then tend to conclude it's true."

    Class in college .. here's a photo. Everyone looks at it.

    There's a young man in a cap and gown with what appears to be a diploma. A smiling man is standing to one side, a smiling woman to the other and in the forground is a girl about 12 looking bored.

    Assertions, true or false: The father is proud of his son. The graduate's younger sister wants an ice cream. The mother is very happy.

    The first assertion is not necessarily true (therefore false), how do we know the smiling man is father, uncle, family friend, whatever?

    The second assertion is not necessarily true, how do you know she is related to the graduate? Where does it say anything about ice-cream? She could potentially be a young boy with long hair in girls clothing.

    The third assertion, mother? How do we know the woman has children? How do we know any of those present is related. It's also false.

    Quite fasciniating watching the light go on (perhaps for the first time in their lives) of my classmates. I challenged the assertions immediately because, being a rather literal programmer, I didn't see any statements of fact with the photo, so everything had to be assumptions (and who codes on assumptions? Ok.. lots of people do, that's why we have so many security problems, lack of useful feedback when things don't work and poor interfaces.)

    Now consider there are tens of millions of people who haven't even had an introduction to Critical Thinking and they are influenced by advertising, politcal speeches,much of the garbage on talk radio and those evil stinkers who talk young men and women into committing atrocities.

        Critical Thinking is seen as a threat to a lot of groups, as well as some parents. I think this is why such a simple, yet neglected concept is left to college, where it's at the option of the student to take the class, rather than have kids coming home challenging their parents, church and community leaders.

        Abosolutes. There is either True or False, not being proven to be True is therefore false. Inserting grey area in between is interesting, to explore possibilities, but when asked True or False, there can be only one.

          "Not (yet?) proven true" is not "false".

          In logic, it's trivial to flip any statement so that your default presumption of falsehood becomes the exact opposite given a different statement

          "John is a liar" -> False, he must be an honest man!

          "John is an honest man" -> False, he must be a liar!

          Same rule, opposite outcomes based on a completely arbitrary starting point.

              "I don't know" is silly in this context, since I would know if I have a wife, and if I had been beating her. But if you shifted the statement to be about a 3rd party where ignorance is a reasonable possibility, then "I Don't Know" would again become a valid response.

    • Your overall point is good but just because something is "not necessarily true" does not make it false. If something is "not necessarily true" it could be true or it could be false, we just don't know which it is. It is a bit of a nit pick and you may have glossed over that for the sake of brevity.

          If the statement "the father is proud of his son" is false, then the statement "the father is not proud of his son" must be true. But it isn't - we simply don't know.

          The only way any of those statements could be asserted to be either 'true' or 'false' is if they are prefixed with something along the lines of "We know from this picture that...". Now your true or false statements are not about the happiness of the father, but wheth

      Perhaps the inclination to answer "true" is related how much information you think the questioner has. If the questioner has a photo of the subject, it is likely the questioner has done more research on the subject and knows the right answer. If the questioner just gives you a typed name, then it seems more likely the questioner just pulled a name out of memory and doesn't know much about the subjects current status.

While it is 100% true that the photo here does not prove the truth of any of the associated statements, none the less if you came across this scene in real life and began interacting with the people in question, you would probably be money ahead assuming the statements are true rather than guessing you have no idea what is going on.

      One interesting thing they suggest is that, since in this study the "truthiness" effect happened in both directions, or even with unrelated images, previous studies showing that images produce a bias might need to be re-run with control images that are unrelated, i.e. placebo images.

      For example, the paper mentions a 2008 paper [nih.gov] that found public trust in neuroscience findings was higher if accompanied by an image of a brain scan. That article speculated that "part of the fascination, and the credibility, of brain imaging research lies in the persuasive power of the actual brain images themselves". But the authors of this paper point out that perhaps it was just the presence of any image at all: what would happen if you re-represented the same articles, not with brain scans, but with just photos of the neuroscientists, or of the MRI machine? The authors hypothesize that you might get more people believing in the results in those cases, too, in which case it wouldn't actually be that the brain-scan images are serving any persuasive or evidentiary role in and of themselves.

    Trayvon Martin and George Zimmerman news coverage.

    When the news story first reported most of the newspapers and news agencies showed the picture of Trayvon in the red shirt and George in an orange jumper. There were other pictures available, so somebody chose these pictures.

    Trayvon's picture was of when he was 12 years old. The picture has a very happy looking kid, with a big smile. Eyes are bright, and the picture is very friendly, very innocent.
    George's picture is of a old mug shot, he was heavy, unshaven, the picture could be lightened or darkened (I've seen lighter and darker pictures, unsure what the original looked like). George is not smiling, unhappy, depressing.

    Now there is a headline "Man kills teen" and phrase "Man kills in self-defense"

    With the images provided we make assumptions.
    The Trayvon is 12 years old. False, Trayvon is 17.
    George is a convicted felon/criminal. False, George was arrested, but charges were dropped (yes I know there is some claims on this, but the charges were dropped.).
    George is white, Trayvon is black, this is racism. False, George is Hispanic. George is known for tutoring black children for free on the weekends, and was the only person to come to the defense of a homeless black man. The FBI investigated George and found no evidence that he is racist in any way.

    So, the images and headline imply the idea: "White racist convicted felon kills innocent happy black child."

    Other shading comes from the text - small example: Using "Trayvon" and "Zimmerman" for names. "Trayvon" is a very "black-sounding" name. Zimmerman is a common German name (Germans aren't known for any racists right?).

    And the damage is done. People have picked sides and have dug themselves in. Even now when we have up-to-date pictures (few are using the old red-shirt/orange jumper pics), the original images have set themselves in the minds of the people. What would have the story been like if the media outlets used the up-to-date pictures, rather than the kid/convict pictures?

The context you build can be so strong, that when presented with facts pointing you are wrong, some people still own't believe the truth over there made up context.

  • This doesn't have anything to do with "pictures" in particular. You can ask someone a question that requires them to prioritize ethics or results about their job and they will choose a different path depending on if you've recently asked them an ethical question vs a results prioritizing question. You ask someone to pick a different colored card from a table in a sentance that contains a word that rhymes with one of those colors... same result. This is just how the mind works. You bring something to th
  • There was an interesting study conducted built around the recent research on Eastern and Western cognition. People were initially "primed" with a series of photos relating to one culture or the other. For example, people from East Asia who had previous exposure to Western society were shown pictures of cowboys and the Statue of Liberty while Westerners who had experience working with East Asians were shown images representing Eastern culture like pagodas and pandas. They were then immediately provided wi
  • I'm writing all my essays in Baskerville with included pictures from now on. I'm sure that will go down really well for my next funding application -- do graphs count as pictures?
