You want to make sure to space everything out on your website page, so that it doesn't look really cluttered. Using the space makes everything easier to see and it looks better for the user.

It is important to use rhetoric to create designs that appeal to the customers. Using rhetoric you can build upon your original designs and add more ways to benefit the user, which helps make sure more people continue using the product.

An example of loss aversion would be a store putting out a big limited deal, to make people think they would lose more by not buying anything, even if its something they don't need.

The brain can only store so much memory, so overloading it with information causes it to be more difficult for someone to understand things. So if a website is too cluttered with information and buttons, the user is going to struggle, versus having a simple design, makes it easier for the user.

People rely too heavily on the first piece of information they see, for example if you're shopping and see an item for $200, then see the same item for $150, even if the $150 is overpriced, it still seems like a good deal because the first price seen was $200.

The Position of the items affects how we remember them. This is due to Primacy Effect, which is the tendency to remember items at the beginning of a list more easily, and Recency Effect, which is the tendency to remember items at the end of a list because they were the most recent items we saw.

Fitt's law basically means that the time it takes to get to a target, such as a button, depends on the size and distance. So if a button is far away and small, it will take longer to get to the button.

When there are more than one decision, your brain has to evaluate each option, and compare them. For example, when ordering food, the more items on the menu the longer it will take to decide what to order.

The goal is to heavily give information that supports their beliefs and give a lot less information that contradicts it, since people like to hear things that support what they believe in. This happens a lot in politics.

Since people remember pictures better than words, it is very useful to make sure to have good images that go with your product, and worth it to put extra time into an image that represents your product well.

If an update comes out with lots of big changes, it can cause a lot of people to not like it. There are a good amount of people that don't like lots of change, especially when they get comfortable with a product, so a big update can create some backlash, but breaking it up into small changes over time make it seem like not much is changing.

This effect can be used to get more people interested in a product. When something is supposed to be kept a secret it causes more people to look and notice it, so creating a product but hiding details about it can help more people become interested in it.
