The particular context in which it was used last week related to news: how and why certain people attend to certain news sources. People, so the argument went, are hardwired to seek out arguments and evidence with which they agree, and when they do happen to encounter counter-attitudinal arguments and evidence (i.e., stuff with which they don't agree), they are hardwired to interpret it as biased. When used in this context, what does "hardwired" really mean?
Hardwired reactions to stimuli in our environment are automatic and, as the metaphor would suggest, more-or-less permanent. Hardwired cognition/behavior are the products of adaptive processes that occurred over thousands of generations. We are born with these reactions; we don't need to be taught. Our startle reflexes, our orientation to faces, and our fear of spiders are all hardwired. Then there are reactions that are learned and, through repetition and conditioning, become automatic. It's easy to just lump both of these kinds of reactions together because they both involve automatic, quick processing of information without any voluntary control. But the hardwired reactions, I think, are harder to change than the automatic learned reactions because they have been around longer.
So let's assume that the aforementioned tendencies relating to news are, indeed, truly hardwired. None of us had to learn to seek out evidence we agree with and to view evidence that we don't agree with as biased. These information processing strategies evolved over many generations. Perhaps they're extensions of our need to preserve a stable sense of self or a coherent picture of our environment and where the rewards and threats lie or our social standing within a group of allies. This leaves us with a few important (and oft ignored) questions about our hardwired reactions to our information environment.
Can hardwired reactions to stimuli be "rewired"? Not easily, if at all. I don't think you could condition folks to seek out counter-attitudinal news and expect them to pass this tendency on to their offspring through their genes (which is what I take "rewired" to mean).
Can hardwired reactions to stimuli be overridden? Yes. Actually, I think this happens all the time. All of civilization, it's been said, is a kind of imposition on many of our hardwired reactions to stimuli, an attempt to override and otherwise control (i.e., repress) reactions that would be destructive in the long run to large numbers of people trying to live together (i.e., society). The repression of impulses is so ordinary that we forget the many ways the contours of society keeps them in check, through laws, rules, social mores, and restricted availability.
How strong is a hardwired predisposition? Put another way: how hard would it be to override a hardwired reaction to stimuli? This is another case in which the question of magnitude (what I like to call the "how much" question) is ignored, and I think it's ignored strategically. If you ignore the fact that some hardwired reactions are far easier to overcome than others, you could say that an inborn impulse that is not that hard to control is just like another inborn impulse that is almost impossible to control - they're both "hardwired". If it's somehow to your advantage to say that some behavior is unchangeable (say, if you're defending ideologically polarizing news coverage because it caters to our hardwired orientation toward information), you'll note how it's hardwired and leave it at that.
Just how hard is it to change behavior that is hardwired depends on the behavior, maybe on when it evolved and what's at stake (i.e., how great the reward or punishment for behaving in ways inconsistent with the predisposition). You can get most people to overcome their hardwired desire for sweets easier than you can get them to overcome their hardwired desire for sexual gratification or desire for novel stimuli or inclination toward competition or cooperation. Hardwired reactions or behaviors vary in the extent to which they are capable of being overridden. It is possible to know how hard it is to change a particular hardwired behavior through experimentation.
What the heck does this have to do with software?
The design of software affects what types of information are available to us in certain places at certain times. There are various reasons we're averse to the idea of restricting availability of information in any way. Information is speech, and speech should be free. More information and more freedom to choose just seem like inherently good things. But really, our access to information is restricted, in some sense, all the time. We see a fraction of all available information, if only because we can only process so much information and the amount to which we have access via the Internet has grown exponentially. The fraction of the total news information to which we pay attention is determined primarily by the aforementioned hardwired reactions to stimuli and software that makes certain information available to us based on our prior impulsive behavior (i.e., what we click on without thinking too deeply about it). Perhaps our hardwired reactions to stimuli determine our news consumption behavior not because they're all that hard to change, but because nothing bothered to stand in their way.
Here's some good news: experimenting with information environments is actually much easier than experimenting with our environment in general (i.e., the one we walk around in everyday). Simply installing browser extensions can remove ads from our information environment or restrict access to whatever websites we choose. Algorithms can recommend counter-attitudinal news stories. Installing a "Respect" button on comments sections, next to the "Like" and "Recommend" buttons, can increase the likelihood of exposure to counter-attitudinal messages.
You can't get rid of those hardwired impulses to seek out information we agree with. But can you override them? I don't think we've explored that question fully yet.
The discussion of hardwiring gets at an important underlying issue: how fixed are any of our characteristics? It's an emotionally loaded question. There's a lot at stake. But it's exciting to be able to explore the possibilities of changing ourselves and our hardwired impulses by changing our software.
