This is what happens when you google "misinformation". |
You would think that search engines such as Google would help in separating the bunk from the good stuff. However, as recently reported in the New York Times, that is not necessarily the case and the algorithms themselves may lead to bias. I decided to do a bit of an experiment and was able to recreate the image search referenced in the article.
If you do a Google image search, indeed, the first woman that appears is Barbie. |
In case anyone is wondering, the above is NOT how genetic engineering is done. In 20 years of working as a research scientist I never once used a needle to inject genetic code into anything for the purposes of genetic engineering. That's not how it works. And while in my garden I have spliced apple tree branches to other trees, I never never seen an apple spliced to a pear using stitches. If you want to know how the process is done and what actual genetically engineered crops look like, I encourage you to go to GMOAnswers and ask questions. It's okay to have and to ask questions. It's not okay to present the entire field of study as it's depicted above.
Next, I wondered what would happen if I googled "organic".

Notice how everything is green and calming and pleasing to the eye. Considering the huge difference from the GMO search, you can see a very clear bias toward organic.
Now what happens when you google "GMO farm"?

So what happens when you do a search for "organic farm"?

But that's not the end of the story. I also wanted to see how livestock farming was portrayed. At this point no one will be surprised by the results.

You might be wondering what the deal is with grass fed beef as opposed to grain finished. Most US raised cattle cannot be 100% raised on grass simply because winters (and sometimes summers) are harsh where the cattle are raised. When the grass is frozen over, dead due to a heat wave, or simply of insufficient quality to support livestock, the owners of those animals will bring in forage (e.g., hay, alfalfa, etc) and grain to supplement the animals' diets. There are small scale 100% grass fed operations in the US, but most of the grass fed beef in the US comes from Australia. Animals that are not grain finished or even grain fed tend to have less fatty meat. Some, but not all, consumers prefer this and will pay a premium for it. Grass fed animals also tend to take longer to go to market because it takes longer to get to market weight.
So what happens when I search "organic livestock"?

Through all of this, I wondered what other topic would show a similar bias.
Google image search for "vaccine". |
Google image search for "public health". |
Vaccines aren't the only component of public health, but they're a hugely important aspect of it. Vaccines are used to prevent or reduce the likelihood of infection from preventable illnesses, such as measles, diphtheria, and influenza. You might be wondering why displaying vaccines as needles is a bad thing, since the majority of them are delivered via needle and syringe. Simply put: many people are afraid of needles. By demonstrating the public health and disease prevention benefits of vaccines you can present their purpose without instilling fear. Groups that are against vaccination use this fear to their advantage to the detriment of general public health.
So what does this mean to the average person, who is not an expert in any of these fields and who just wants to find reliable information online? It means a few things:
- Be aware that there is considerable bias in how information is presented. Look for the bias, which is usually depicted as "good versus evil" or "us versus them". Reality is very rarely so black versus white or one versus the other.
- As more and more entertainment and information is being pushed online and everyone is becoming more media savvy, I suspect this will become an increasingly important issue.
- Watch out for Appeals to Emotion in the information being presented. We have a tendency to want to believe the person who is most passionate when delivering their arguments. However it's very easy to be passionately misleading about something.
- Watch out for Appeals to Nature in the arguments being presented. Natural isn't always better, although sometimes it might be.
- When experts in the field argue or disagree, try to find out the basis for the argument and find the common ground. If possible ask them to explain the topic or to lead you to resources that better explain it.
- Academics love to argue. If you come from outside of academia, look for the scientific consensus. This may change over time, but the consensus typically leads to the best interpretation of the currently available evidence. [Scientists must justify conclusions that deviate from the consensus with evidence. If they don't provide evidence, or sufficient evidence, those findings are discarded. If someone is clearly blowing smoke without evidence, other scientists will let them know.]
In the end, remember that it's okay to have and to ask questions. It's how people learn.
I have complained to Google about their search results before and how they give more weight to the pseudoscience and woo sites for articles and news stories. They at one time made a vague statement about giving a ranking boost to actual science and education sites, but so far have seen little evidence of that.
