Shortcuts: Multitasking

(This post is part of a series. Intro > 1. Illusions > 2. Labeling > 3. Math > 4. Multitasking)

This one combines the worst of Illusions and Math. We trust our senses and inadequately assess risk.

We have limited capacities for attending to what happens around us. Two or more objects are not being held at the same time in memory. We switch between them. Once we have copied them from long term or permanent memory into working memory then short term, we can find those copies pretty quickly again. The more complicated the behavior and the more dissimilar the two or more tasks, the worse we multitask. By worse, I mean we are more prone to error and take longer time.

Given all the research and media coverage on how bad we are at multitasking and risks associated of texting and driving, I see people doing it daily. A law here allows police to write tickets to people who do it for the past few years. Texting is also pretty bad even on hands-free devices. Like other risky behaviors, these approaches are unlikely to stop humans from putting themselves in dangerous situations.

Behavioral economics fascinates me. Humans have amazing abilities to miscalculate risk with extreme confidence they accurately assessed it. These appear to be rules of thumb which work in certain situations, but really are not applicable to others yet most people do.

Part of the problem gauging risk, I think, comes from a lack of consequences in low risk situations. Switching from writing a script to answering an email and back while sitting at my desk is extremely low physical risk. Switching back-and-forth between driving and answering a text message can seem like no big deal when even 23x more likely to have an accident is still one in thousands. A lack of having an accident or close call while driving is seen as evidence of the ability to text and drive without a problem. (After all how risky is it operating a car of several hundred pounds?)

Following the causal chain of events presents us with problems. We sometimes pick the wrong causes. We then are more likely to pick that wrong cause over and over. Logic and science are tools invented to combat these problems. Testing the idea with large samples eliminate variation as a confound. Others testing with the same or slightly different experimental designs point out the relevant scope.

“Garbage in; garbage out” can also trip us. We poorly assess the reliability of inputs from illusions I discussed earlier, so the calculations based on garbage were never going to be good anyway.

Strangely enough slowing the process down and thinking about it from many different angles can even exacerbate the problem as we get mired in so much data or processes we cannot make a decision.

Technology helps us do the same calculating just faster. Some helps us validate the outputs. I look forward to technologies that help us identify the correct inputs. My big beef with predictive analytics is doubt the correct inputs are being identified, so the outputs might have lots of garbage.

Shortcuts: Labeling

Homo Sapiens Sapiens cheated evolution in one critical way by creating language. Rather than rely totally on instincts passed along by genes, we pass along an enormous amount of information to our proteges through memes. These may not even be the descendants of our genes. In working together on something, we share enormous amounts of information.

Everything including physical objects, ideas, and behaviors all have a label. Sometimes more than one. A label is a way of identifying something without having to go into the gory details of explaining it every time. (Like I just did.) I can call something an “apple” and anyone who understand this word knows what I mean. Labels bring efficiency to language. Until it does not.

Framing and metaphors are a couple of the tools behind labels. Through them labels acquire properties which then influence how we think. We can be manipulated by these thoughts simply by others choosing one label or the other. A great experiment has test takers write random number at the top. The larger the number, the better the test takers did on the test. How a question is phrased in a poll skews the responses. When we use metaphors also we constrain our thinking. Using the metaphor of a clockwork universe makes us think of mechanical devices and how everything around us are such devices.

Maybe English is a special case. Between Frisian (the ancestral language that make English belong to the Germanic family) and French from the Norman Invasion, English has multiple words for things. Throw in the Melting Pot that is the United States with making up jargon for everything. This language is an absurd mixture of strange meanings. Certain words like “set” have so many definitions one needs to hear or read it in context to understand it.

Then we also have LABELS. LABELS are also labels but have the special nature of how we classify other people. They are how we split people up into groupings to say one is not like another. White vs Black. Extrovert vs Introvert. East Coast vs West Coast. Democrat vs Republican. All are arbitrary. Many are misunderstood. They drift into caricature stereotypes causing hurt. This is where our -Isms arise. Nationalism, racism, or sexism would have no place without powerfully overly broad LABELS. As our conversations become more mature, we need more and more LABELS to express the nuances even while others resist change.

We need labels in order to communicate with each other. We just need to recognize their fallibility. And somehow avoid hurting each other while expressing ourselves.

Shortcuts: Illusions

(This post is part of a series. Intro > 1. Illusions > 2. Labeling > 3. Math > 4. Multitasking)

We like to think only those things we experience exist. Or even can experience. What about those things we can experience that do not or never did exist? That is what illusions are. They are cases where we trick the brain into believing something happened that did not. Or tricking the brain into thinking is experiencing reality when it is missing crucially important.

Michael Bach has a nice optical illusions page to demonstrate how easily our eyes are tricked. Every sense we have can be tricked. The food industry has worked wonders in devising how to trick our senses of smell and taste. When you feel something crawling on you and look to see nothing, that is your sense of touch going haywire.

Illusions can also be dangerous. Eyewitness testimony is the worst evidence we use in the legal system. Witnesses rarely capture and retain all the details. And how they are interviewed can allow them to fill in these gaps with other evidence and skew their results to confirm that same evidence. Say the police pick up a suspect and present that photo with others to a witness. The witness picks the photo of the suspect and later out of a line up. If the suspect actually only resembles the culprit, then these two steps confirm for the witness (and the police) the suspect’s guilt even though the witness saw someone else. We attend to similarities when searching and ignore the differences. And we will go with the closest option given choices.

Inattentional blindness also falls into my illusions category. Paying too much attention to something means we have no idea about what else is happening. The train operator on his cell phone not noticing the curve for which he needed to slow down and derailed. Multitasking while operating a vehicle is dangerous because of this.

Of course, everything we experience is really the interpretation of signals to the brain. One of my favorite experiments was people wore goggles that inverted the image so everything appeared upside down. The brain just adapts to the error and interprets the picture to the desired orientation. Do not like what you see? The brain can solve that problem. Another favorite experiment was ending phantom pain in missing limbs by using mirrors to make the limb appear to exist again.

My favorite metaphor for how the brain works is Object-Oriented Programming. Different parts of the brain perform different functions. The functions adapt (are reprogrammed or reconfigured) based on the needed interpretation of the data. Of course, the adaptations are not always 100% correct. Nor do they always adapt in time not to avoid errors.

Shortcuts: Intro

We humans laud our superiority over the rest of the world. We even claim to be better than other humans. The chief attribute we compare is intelligence.

An interest of mine regarding Psychology in college was failures of the mind. Phineas Gage suffered a brain injury that drastically changed his behavior. That was really cool! Yet, that and other cases are relatively rare. More universally, the brain works much more nuanced than most people give credit. I think much of the problems of society tie back to how the brain works and maybe even societal attempts at glossing over the limitations.

Rather than one really long post, I am going to break these up into several. And much of this has been bumping around in my head for months, but I took a few hours to lay it all down.

    1. Illusions
    2. Labeling
    3. Math
    4. Multitasking
    5. Rules

For going on a decade, I have called these Cheating. Rather than taking in all the information, completely processing it, and strategically acting upon it, our brains selectively attend to a small portion, throws out even more, and acts upon incomplete information. Most of the time it works. Much of the time it doesn’t and we have no idea so we just think it works. Every once in a while we get burned by our brains not following the rules we expect them to follow. So to make this more palatable, I am going to try calling these Shortcuts.
