Teaching needs an ecosystem that supports evidence-based practice. It will need better systems to disseminate the results of research more widely, but also a better understanding of research, so that teachers can be critical consumers of evidence.

The value of a scientific publication goes beyond this simple benefit, of all relevant information appearing, unambiguously, in one place. It's also a way to communicate your ideas to your scientific peers, and invite them to express an informed view.

If a scientist sidesteps their scientific peers, and chooses to take an apparently changeable, frightening and technical scientific case directly to the public, then that is a deliberate decision, and one that can't realistically go unnoticed.

I've always been a bit of a decorator. I think if I wasn't a singer I'd probably be in stage setting or interior design or something. I like clutter and I'm quite visually greedy.

I wanted to create a toolkit which I would have wanted as an entrepreneur to use these principles of psychology in product design. Some startups totally forget the trigger. In some, the action is too complicated. Others don't have a variable reward, which maintains mystery.
