Have you ever been to a pub with the intention of doing just a few drinks and going home early, only to stay until closing time? A lot of people probably have. If you are one of them, have you ever wondered why you've indulged yourself much more than intended? There are several excuses you could tell yourself to justify staying longer than you should have. Maybe it was a really good night out and it would have been a shame to miss it. Maybe the DJ was playing your favorite music. Or maybe you're just bad at planning.

A less common excuse is the dim lighting in the pub. Few people will believe you if you tell them that your hangover is caused by the lighting in the pub. However, research has indicated that this may have a significant effect on your night out after all. It turns out that the amount of light does more than just setting the atmosphere.

Each and every day, package designers, retail planners and online UX experts all face the same question: should you follow customer expectations, or should you break them?

Many experts propose that stores, products and websites should strictly adhere to what the customer expects. This would increase the fluency of the customer experience, leading to increased feelings of positive emotion and – ultimately – purchase behavior.

Nonetheless, there are countless examples of successful concepts that had their rule-breaking philosophy to thank for. From Dell cutting out the middle man in an industry where no one believed people would buy any place else than the retail store, to Craigslist proving discarding many emblematic UX and design rules.

In the modern world, we hear a lot about crowdfunding: it helps small and medium companies to generate a budget for their products and achieve popularity by promoting it via various Kickstarter-alike platforms. But what about crowdsourcing? While crowdfunding assists in gathering money for projects, crowdsourcing helps with getting consumer-derived ideas for new products. People tend to reject the practice of crowdsourcing, considering it as less effective. Judge the numbers: 9.65 million of Google search results for “crowdsourcing” versus 36.3 million for “crowdfunding” – demand creates supply, and the “shortage” for “crowdsourcing” says a lot.

Crowdsourcing becomes more interesting if it can also bring financial benefits and boost your sales. How? By applying it wisely, of course.

Generally, when visiting a supermarket, you don't want to waste your precious time by searching for the products you're looking for. In order to help us making decisions, our brains have a few biases in their way of seeing things.

We all know that marketeers are trying to get their products in the centre of a display, and that’s for a very good reason. However, new research shows that there’s another bias that influences our way of checking products. Apparently, our visual attention tends to automatically focus to the upper part of a display when we’re looking for a light-coloured product, and to the bottom for a dark coloured product.

There are only 24 hours in a day for us to get through our to-do lists. So how do we decide what to prioritize? Lucky for us, our brains use cognitive shortcuts to simplify decisions and cut corners. But here’s the catch: cutting corners has consequences. And when it comes to our brain, cutting corners leads to cognitive biases.
