Is Google making us know-it-alls?
The internet has a reputation for harbouring know-it-alls. Commenters on articles, bloggers, even your old school friends on Facebook all seem to swell with confidence in their understanding of exactly how the world works (and they are eager to share that understanding with everyone and anyone who will listen). Now, new research reveals that just having access to the worlds information can induce an illusion of overconfidence in our own wisdom. Fortunately the research also shares clues as to how that overconfidence can be corrected.
Specifically, we are looking at how the internet affects our thinking about what we know, a topic psychologists call metacognition. When you know you are boasting, you are being dishonest, but you havent made any actual error in estimating your ability. If you sincerely believe you know more than you do then you have made an error. The research suggests that an illusion of understanding may actually be incredibly common, and that this metacognitive error emerges in new ways in the age of the internet.
Part of this phenomenon is the tendency to then confuse what we really know in our personal memories, with what we have easy access to, the knowledge that is readily available in the world, or with which we are merely familiar without actually understanding in depth. It can feel like we understand how a car works, the argument goes, when in fact we are merely familiar with making it work. I press the accelerator and it goes forward, neglecting to realise that I dont really know how it goes forward.
Fisher and colleagues were interested in how this tendency interacts with the internet age. They asked people to provide answers to factual questions, such as Why are there time zones? Half of the participants were instructed to look up the answers on the internet before answering, half were told not to look up the answers on the internet. Next, all participants were asked how confidently they could explain the answers to a second series of questions.
People who had just been searching the internet for information were significantly more confident about their understanding of the second set of questions. Follow up studies confirmed that these people really did think the knowledge was theirs: they were still more confident if asked to indicate their response on a scale representing different levels of understanding with pictures of brain-scan activity (a ploy that was meant to emphasise that the information was there, in their heads). The confidence effect even persisted when the control group was provided answer material and the internet-search group was instructed to search for a site containing the exact same answer material. Something about actively searching for information on the internet specifically generated an illusion that the knowledge was in the participants own heads.
If the feeling of controlling information generates overconfidence in our own wisdom, it might seem that the internet is an engine for turning us all into bores. Fortunately another study, also published this year, suggests a partial cure.
Amanda Ferguson of the University of Toronto and colleagues ran a similar study, except the set-up was in reverse: they asked participants to provide answers first and, if they didnt know them, search the internet afterwards for the correct information (in the control condition participants who said I dont know were let off the hook and just moved on to the next question). In this set up, people with access to the internet were actually less willing to give answers in the first place than people in the no internet condition. For these guys, access to the internet shut them up, rather than encouraging them to claim that they knew it all. Looking more closely at their judgements, it seems the effect wasnt simply that the fact-checking had undermined their confidence. Those that knew they could fall back on the web to check the correct answer didnt report feeling less confident within themselves, yet they were still less likely to share the information and show off their knowledge.
So, putting people in a position where they could be fact-checked made them more cautious in their initial claims. The implication to draw from this is that one way of fighting a know-it-all, if you have the energy, is to let them know that they are going to be thoroughly checked on whether they are right or wrong. It might not stop them researching a long answer with the internet, but it should slow them down, and diminish the feeling that just because the internet knows some information, they do to.
