My great mate Marcos Benevides put me onto a really interesting article last week through a Facebook blip: How facts backfire.
It's a cracking read and explores research showing how, rather than changing our views on issues based on the presentation of facts that directly disprove them, we are actually more likely to reject the new information outright and strengthen our belief in our previous position.
If you have the time, I invite you to have a good look at that article and then share your thoughts here about how similar the findings are when it comes to:
A) convincing co-teachers or school management they are doing something based on information or assumptions that are factually flawed
B) convincing learners that there could be a better things for them to use or focus on in the language classroom, and/or better overall strategies that could assist them in learning
