Backfire Effect Not Significant

Previous research has shown that when confronted with a factual statement that appears to go against an ideologically held belief, a percentage of people tested will move their position away from the factual information – a so-called “backfire effect.” This notion was rapidly incorporated into the skeptical narrative, because it seems to confirm our perception that it is very difficult to change people’s minds.

However, more recent research suggests that the backfire effect may not exist, or at least is exceedingly rare. A recently published series of studies puts a pretty solid nail in the coffin of the backfire effect (although this probably won’t be the last word).

To be clear, people generally still engage in motivated reasoning when emotions are at stake. There is clear evidence that people filter the information they seek, notice, accept, and remember. Ideology also predicts how much people will respond to factual correction.

The backfire effect, however, is very specific. This occurs when people not only reject factual correction, but create counterarguments against the correction that move them further in the direction of the incorrect belief. It’s probably time for us to drop this from our narrative, or at least deemphasize it and put a huge asterisk next to any mention of it.

VR is the Future

Published by under Technology

I have written about virtual reality (VR) before, but over the break I acquired my first VR headset so now I have experienced it for the first time. It is better than I imagined.

It is still to early to make firm predictions about how the technology will be used, but my personal experience has definitely upgraded my optimism. First let me talk about the experience itself, and then we can delve into possible applications.

In case you are not aware, VR involves wearing a headset that completely covers your vision and fills your visual field with a 360 degree 3D digital reality. In addition there are sensors which can read your location in the room and sense your controllers as well. You have to setup the space so that the system knows where the edges are. You can move about freely in the space, and virtual gridline walls will appear to warn you that you are approaching the edge.

The first thing I noticed when I activated the VR software is how completely natural it felt. I was a little surprised, actually. I had some fear that it would be a bit disorienting and I guess I assumed it would feel artificial, perhaps primed by how the tech is sometimes portrayed in Sci Fi.
