You could easily do home organizing for people, an industry that has gained a lot of popularity since the debut of Netflix's hit series Tidying Up with Marie Kondo. If you're a tidy and organized person yourself, and you're good at organizing spaces, why not offer your services to people around you? You'd be surprised at how many people, even on your own social media feed, might take you up on doing something like this.
The ego is the driver making the decisions. It decides between the devil (the id) and the angel (the super-ego) on either shoulder (yes, all those cartoons you've ever seen are partly true). We have voices in our mind, and it's up to the ego to decide which one to fulfill. Its goal is to satisfy the id in some way while also attending to the super-ego.
I concluded that having read a product review, people felt more informed to make a purchasing decision. As a result, if they did click a link after reading the review they were more likely to buy the product. Those clicking on the top link seemed to be more in a ‘surfing’ mode. They clicked on the link less because they wanted to buy it but more out of interest to learn more. Some bought the product and some bought other products once they were ‘in the door’ at Amazon.
