ixDa SF @ Armory: Social design patterns

2 comments

Here’s a list of takeaways from the presentation:

  • There were several connections between architecture and social design. Both create an ecosystem (one physical, the other virtual) which people act within and on.  The designer’s role is to “pave the cowpaths” – chart out the area with paths for its intended use.
  • Because of the duplicity of names, users require more complex forms of identification besides name. This can be a picture, badges, biographical info, etc.
  • talk like a human. Designing a social interface should be different than designing a bank transaction. No robo-speak allowed.
  • Related to watching how you speak, designers should consider the difference between “me” and “you”.  In the world of social media, propriety of information is still a gray area which one should be sensitive to.
  • Competition can be good, if you want to foster competition, otherwise people will game the system for no purpose besides being on top.
  • Pay attention to the organic use of your social system, e.g. Friendster failure– fake profiles emerged because people wanted to create associations around things other than real people.
  • Related to fake profiles, social media should refer to some social object, an “aboutness”.  Once a user creates a profile, then what?
  • Important questions: What is going to be the behavioral norm? What about your power user? Your system has to accomodate the user who never adjusts anything from the defaults but also the user who wants to explore every last feature.
  • Humans are unpredictable.

Are design & psychology subjective disciplines?

leave a comment

photo by Francisco Antunes

If you’ve ever been called out for “being subjective”, then you know how frustrating it can be. It seems hardly fair that after performing research and forming reasoned arguments, a colleague or partner can shut you down with one phrase, usually putting an end to any rigorous debate or academic inquiry.

Psychologists and designers suffer from a cliched generalization that we engage in a subjective discipline. This half-truth seeks to invalidate the factual and empirical findings which are made in the field.

Are we, in fact, being subjective? Yes and no. The truth is, you can be subjective while being factual.

In their (and your) defense, let us explore this misunderstood claim:“You’re just being subjective!”

We’re somewhat mistaken in how we use the phrase. Subjectivity comes in two flavors : ontological and epistemological. Lets start by distinguishing the two types.

Ontological subjectivity

A discipline can be said to be “objective” in ontology if it studies phenomena that which exists without human beings, and makes claim that remain true and valid without the existence of human beings:

  • Natural sciences — rocks, trees, oceans, animals
  • Physical sciences — matter, planets, stars, atoms,
  • Chemical sciences — material, reactions,

In contrast, disciplines that are “subjective” in ontology focus on topics that rely on human consciousness, and whose claims will be nonsensical without a human being.

  • Psychological sciences — emotion, judgment, reasoning, action
  • Aesthetic sciences — perception, color, style
  • Philosophical sciences — morality, values, knowledge

Are you being subjective? Well, if you study human behavior and action, you probably are. Designers and psychologists (as well as economists, historians, and similar professions) concern themselves with subjective topics. We find human subjectivity, consciousness and decision making more interesting than atoms. However, that does not mean these studies are not based on facts.

“When a pin pricks my finger, I draw away”.

“This shade of green is present in the works of this period”.

“When making decisions, humans are risk-averse and prefer certainty”.

These claims have a subjective ontology, but are based in factual observation. They are nonsensical without reference to a human subject, but this alone does not make them biased or matters of opinion.

We are not Subjective!!… epistemologically

“Psychology is subjective. Design is subjective.” Attacks on design are not ontological (attacks on our subject matter), but are epistemological attacks, questioning the nature & extent of knowledge that the fields produce. Attacking epistemology is saying our conclusions are rooted in opinion, rather than fact.

I whole-heartedly reject this idea. Investigate the statements listed above, and find me the bias in them. As professional, academics, and progressive thinkers, we hope to eliminate any deviance from hard facts. Do critics really believe that designers & psychologists don’t value facts? We ALSO strive for epistemological objectivity!

Am I confusing you yet? Well, my main point is this: It is wrong is to assume that studying humans means we’re only capable of making opinions. Design is NOT SUBJECTIVE. Psychology is NOT SUBJECTIVE. We make factual claims, though we study areas that require a subjective ontology — a knower, a perceiver, a person with opinions, bias, and willful behaviors. This is the human “subject”.

Designers, stop selling yourself short.

One can study human perceptions, emotions, desires & consciousness without being steeped in bias, assumptions, and opinion. You are engaged in an objective discipline. Various debates have fueled the divide between subjective and objective, to the point that subjectivity has become a dirty word in almost all disciplines. So stop associating yourself with that word. It’s confused and muddled and should no longer be effective as a claim.

The *methods* that they [design and psychology] use are another factor that affects people’s judgment. The “hard sciences” can rely on quantifications more than the “soft sciences” are able to do. This is of course partly due to their respective subject matters. Electrons, e.g., are more “reliable” when being measured than humans are ;-)

-markus weber-

Yes, studying human beings is a bit like trying to hit a moving target. However, we are still able to make factual claims about effectiveness of a design, the persuasiveness of an argument, the likelihood an idea will be adopted. Perhaps more importantly: isn’t the un-reliability of human subjectivity part of the reason these fields are so fascinating? It’s the reason I’d rather study this than engineering.

Your Words Matter: an investigation of linguistic framing

leave a comment

I’ve alluded to framing in two previous posts:

Framing is a potent tool used by marketers, linguists, business strategists, and designers.  What is it?

A frame is simply the body of concepts, stories, scenarios and values related to a term, phrase or idea. Read the rest of this entry »

Jim Jones and the psychology of influence in experiment design

leave a comment

Today’s blog post draws inspiration from Jim Jones, founder of the People’s Temple, who lead a commune of nearly 1000 followers and brought them to their death by suicide (try doing THAT on Twitter).  The massacre at Jonestown shows us how easily the human mind can be influenced and makes a case for how researchers need to guard against it when studying human behavior.

technical tuesday: device feedback

leave a comment

I know it’s Wednesday in most parts of the world (and even Thursday some places), but I honestly could not get my Tuesday blog post out last night.  Despite my best intentions, my house had a power outage due to some exploding transformers which forced me to push this post one day back.   So I’m sorry for the lateness.  Won’t happen again.

The power outage did manage to provide some material for the purpose of this post: feedback.  A device requiring user input usually has a built-in mechanism for providing feedback — a means of communicating a message to the user.  The message could be ‘hey user, the system has received your input’ (the buttons on an elevator); ‘hey user, give us a second we’re thinking about it’ (the hourglass icon in Windows or the progress bar in an web surfing application); or ‘hey you screwed up’ (when you get returned to the same page after entering an incorrect password).  With many means of displaying feedback to the user, some elegant (and not so elegant) designs have emerged.

Feedback can be informative, or can be utterly confusing. After the power was restored, of course all the devices in the house had blinking displays reading the imcorrect times (a method of feedback: blinking = incorrect time setting).  As I went to the microwave to reheat some chicken nuggets for lunch, the screen which normally displays the time was unlike the other time-pieces in the house. It now displayed a cryptic two letter message:

microwavefeedbackPF. What did that mean?  Please fix, promptly find, post-functional, parliament funkadelic?  Provide feedback?  Oh and the microwave worked fine: I cooked my chicken nuggets and the message disappeared afterwards, which further deepened the mystery.  And I still had no idea what was wrong with the microwave or how to fix it.  Bottom line – clear feedback: good for the system, good for the user

monday mentor: Eleanor Rosch

eleanor rosch's Berkeley page - categorical reasoning and cognitive psychologyThis week I take a look at some of the work of UC Berkeley professor Eleanor Rosch.  Rosch created a new paradigm in the field of cognitive psychology, known as prototype theory. Her investigation into the way humans employ categorical reasoning is important to understanding how humans are able simplify the complexity of the world into simple, yet meaningful and distinct concepts.  Anyone working with information architecture, product cataloging, or marketing might want to have heard of her work.

gestural user interfaces

leave a comment

Last month, researchers at MIT unveiled exciting new research developments in gestural interfaces at the TED conference in LongBeach (you can see the video here). In her presentation to the conference, Patti Maes (of MIT) demonstrates a device which reads visual information from the physical environment and uses a projector to create an interface along any surface. This interface is a touchable, interactive display which brings up information about (potentially) any physical item. Representing a quantum leap in the bridge between the physical and virtual worlds, this device has caused professionals and tech-geeks alike to created quite a media buzz. But is such a device more hype than delivery? Read the rest of this entry »
