Affordances and Vulnerabilities

Have you ever noticed how some people seem to be completely “owned” by a device, like a mobile phone for instance, while other people seem to be able to integrate that same device into their lives in a much healthier way? I have friends who constantly check their phones, even when I am trying to have a conversation with them, and other friends who carry a phone but are happy to ignore text messages and even calls when they are having in-person meetings. This also doesn’t seem to be strictly a product of age. Amongst my nieces, nephews, and students, I see the same phenomenon: some are seemingly addicted to their phones, while others are able to treat it as a useful tool that has an appropriate time and place.

In Sherry Turkle’s latest book, which I reviewed in an earlier post, she introduces a pair of concepts that I have found to be very useful in thinking about this phenomenon: technological affordances, and human vulnerabilities.

Book cover for Design of Everyday ThingsThe term ‘affordances’ actually comes from Donald Norman, the cognitive psychologist who wrote the classic book The Design of Everyday Things (a must-read for anyone involved in designing user interfaces). In that book, he defined affordances as “those fundamental properties that determine just how the thing could possibly be used” (9). Affordances give us clues as to how a device should be used: a flat metal plate on a door suggests pushing, while a vertical handle suggests pulling; a button suggests pushing, while a short rod sticking out a right angle suggests flipping.

The brilliance of Norman’s book is how he demonstrates these concepts on the completely mundane and often unnoticed things we use every day: doors, faucets, lights, stoves, teapots, etc. Once you read the book, you’ll never be able to look at these items in the same way again. You’ll also start to notice just how badly designed many of these things are. If a door needs a sign that says “push,” it’s a failure of design, not the users.

This same concept of affordances also works with more complicated devices. Just as the design of a door suggests a type of interaction, the design of a mobile phone (and its corresponding service) or a social networking site can also suggest one or more patterns of use. Designers “inscribe” these patterns into the physical artifacts, and systems behind them, through explicit design choices. Marketers then reinforce those by demonstrating particular patterns of use in their ads. Of course, users don’t have to follow these suggestions, and historical case studies are rife with examples of how consumers have adopted new technologies in ways that were contrary to those suggested by the manufacturer (for example, see the book How Users Matter: The Co-Construction of Users and Technology).

Turkle’s second and related concept is that of human vulnerabilities. Each one of us has particular needs, wants, or addictions that make us vulnerable in particular ways. For example, some people have deep seated insecurities that tend to make them vulnerable to anyone or anything that promises to make them feel more accepted and loved. Others struggle with an overwhelming need for interpersonal connection, and are thus vulnerable to anything that promises to satisfy that. Still others have a deep fear of chaos and are thus vulnerable to anything that allows them to exert control and order over their situation.

When the affordances of a device or system align well with a given person’s vulnerabilities, the results will often be unhealthy for that person. For example, someone with a high need for social interaction but a deep-seated fear of intimacy might find Facebook so alluring that it becomes almost addictive. A person with a fear of chaos and a high need for control will eagerly embrace a mobile smartphone and obsessively check email or the web.

The important point to note here is that this combination of affordances and vulnerabilities is personal and particular. There probably are some vulnerabilities that are truly universal to all humans, but most are not. Some people can walk into a casino, have a bit of fun gambling, and walk out without issue, while others will walk into that same casino and quickly fall into an addiction response. Similarly, some people can carry a mobile phone or use Facebook as helpful tools, while others fall into a pattern of use that enslaves them to the device or service. If affordances align with vulnerabilities, there’s a high likelihood that the relationship will be unhealthy, but if not, it may be perfectly fine.

I like these concepts because they offer a more nuanced way of investigating and critiquing new technologies. Too often we see shocking news articles about “on call” teens that imply this will be the fate of all teens who use a mobile phone. Or we hear a technological critic assert that “Facebook is making us shallow and narcissistic,” assuming that everyone is using it in the same way, and with the same results. These kind of universal statements don’t represent the particular and variable relationships that people have with these systems. They also don’t really help potential users (nor their parents) assess whether they will be able to adopt a new device or system in a healthy way or not.

In order to make that assessment, we need to uncover two things: the affordances (suggested, probable, and possible patterns of use) of the devices or systems in question; and our own particular vulnerabilities. The former is achieved by analyzing and deconstructing the design of the new device or system, and the latter is achieved only by reflection, introspection, and a large dose of self-knowledge and honesty. Both of these are hard to do, and the latter can often be painful, but if we truly desire a more healthy relationship with our technologies, we must endure.

    Very interesting to connect these two concepts. I think you’ve drawn out a tension between the universal commands God has given us (i.e., the 10 commandments) and our particular, individual proclivity to certain sins and our responsibility to consider each. With the former, the burden is on the designer to avoid designing affordances that can lead to sin or harm for a broad group knowing only those broad commandments. With the former, it is the responsibility of each individual to reflect on how a technology may lead them to one of their particular sins.

    I suppose none of us (designers and users) are “off the hook.”

    Thanks for your comment Lee! Yes, I definitely agree that none of us are off the hook when it comes to thinking about the human-built world. The design process is rarely neutral, and I think it often takes fellow technological practitioners to deconstruct a new device and highlight the design choices that were made, and the way they might suggest or encourage particular patterns of use.

      I’m new to your blog so maybe you cover this elsewhere, but do you have any thoughts on teaching future designers about how the design process is not value-neutral? I suppose some of that comes in for engineers when we talk about sustainability, but efficiency and cost effectiveness are the typical “values” I encountered in my time in university.

        I haven’t yet written on that, but this sounds like a great topic to think about. Introducing the concepts of ‘affordances’ and ‘patterns of use’ would of course be a good start, but we need to develop a series of examples and case studies that can give these concepts some concreteness. There is some great literature on ‘domestication’ in media studies (and some in STS as well) that tells stories about how cultures have shaped particular devices to be more in line with their social values. I’ll think more about this and cover it in future posts.

    Thanks for this clear explanation, Dave. Of course our vulnerabilities are precisely what some designers (or at least the marketers of their products) are hoping to exploit. The more addicted we get to things like Facebook or smartphones, the more money those companies can make from us, whether directly or indirectly. Since we, as users, know this, we have all the more reason to want to discern our vulnerabilities and their relationships with certain affordances.
