Answer:
a. Students end up doing "all-nighters" just to finish a term paper.- Planning Fallacy
The Planning fallacy is a tendency by humans to overestimate how much time they have to complete a project due to them having an optimism bias when projecting how much time will be needed. The students thought they had time to study up until they didn't.
b. The so-called "Lake Wobegon effect" where everyone in a group claims to be above average. - The Overconfidence Effect
The overconfidence effect leads people to believe that their abilities exceed what they actually are and can be called the Lake Wobegon effect which was derived from the name of a fictional town where every child was supposedly above average.
c. People who are usually very neat tend to litter in areas that are covered with graffiti.- Framing effect
The Framing effect refers to a cognitive tendency by people to make decisions based on the how it is presented to them. The places covered with graffiti appeared dirty to them so them chose to litter there.
d. Behavioral economists suggest that brand loyalty can be a source of monopoly power for producers. - Status quo bias
This supports the old saying, "if it isn't broke, don't fix it". This bias is an emotional one that leads people to stay in a condition that they are used to because it is what they know and anything else might be considered a loss to them. Therefore companies can use these to always sell to a group of people if those people have brand loyalty.
