Gil Bouhnick writes a blog called The Mobile Spoon: Exploring product leadership, user experience, development, and entrepreneurship. He posted a two-part explanation of 84 cognitive biases. Part 1, Part 2.

Number 4: Von Restorff Effect (Isolation Effect). « When multiple homogeneous objects are presented together, the object that differs from the rest is more likely to be remembered. Design tip: Make sure the CTA button stands out using a different style, size, color, and position. »

Number 17: Base Rate Fallacy (Base Rate Neglect). « We tend to ignore general information and focus on specific cases.  How to use: don’t just share cold information about your product. Instead, show testimonials, use cases, from people or companies others can relate with. »

Number 47: Decoy Effect. If you have a $9 option and a $19 option, the second one looks expensive. If you add a $49 option, $19 looks attractive.

Number 62: Post-Purchase Rationalization. « A great timing to ask a user to share the product (or add a review) is right after the user makes a decision to purchase that leads to a successful transaction. This moment combines a successful experience with the choice-supportive bias. »

Number 79: Primacy Effect. « Items at the beginning and at the end of a list are more easily recalled than items in the middle. UI tip: if you plan to show a long list of items – make sure the first one is your most important item. »
