Our Cognitive Bias

Premise 1: I can’t explain or imagine how proposition X can be true.

Premise 2: if a certain proposition is true, then I must be able to explain or imagine how that can be.

Conclusions: proposition X is false.

... and to bring this up as part of an argument. The issue with doing so occurs when this incredulity isn’t justified or supported by concrete information, and when this lack of belief is used in order to assume that a preferred personal explanation must be the right one, despite the lack of proof.

At the same time, it’s also important to remember that it’s possible that the person using the argument from incredulity is right, despite the fact that their reasoning is flawed.

• It fails to take into consideration all the available information
• It presents information in a misleading way.
• It might lead to improper analysis and might cause someone to paint a misleading picture of a certain outcome.

Also referred to as Bernoulli’s maxim, it states that, when assessing the probability that a certain hypothesis is true, we must take into account all the available information.

"The law says you should drive on the right side of the road, and the law is the law."

When someone is questioning this statement, they are questioning the law. If we say, "because that is the law," we are begging the question. We are assuming the validity of what the other person is questioning.

The most simple form of begging the question: A is true because A is true.

Circular reasoning can also be a bit longer:

• A is true because B is true, and B is true because A is true.
• A is true because B is true, and B is true because C is true. C is correct because A is true.

• If your audience is likely to disagree, speak faster. It gives them less time to form their own counterarguments and you have a better chance of persuading them.
• If your audience is likely to agree, speak slower. It gives them time to evaluate your arguments and factor in a few of their own thoughts.

Gaining agreement has an enduring effect, even if only over the short term. So instead of jumping right to the end of your argument, start with statements or premises you know your audience will agree with. Build a foundation for further agreement.

• The equivalence exaggerates the degree of similarity. I.e, stating that two people share a specific personality trait, but ignoring that they differ in other aspects of this trait.
• The equivalence exaggerates the importance of the similarity. I.e, focusing on a personality trait that two people share while ignoring that many other people also share this trait.
• The equivalence ignores important differences.
• The equivalence ignores differences in orders of magnitude. 

• Show that the similarities between the things being equated are exaggerated, overemphasized, or oversimplified.
• Highlight the differences between the things being equated. 
• Explain why these differences are more significant than related similarities.
• Provide counterexamples.
• Ask your opponent to justify why they believe that their equivalence is valid, and then demonstrate the issues with the reasoning they provide.

Opportunity cost in non-financial situations is more difficult to quantify. The loss or gain with choosing an option while foregoing another can be subjective and not readily comparable.

Example: While deciding on which job offer to take, we may consider job satisfaction, brand name, commute time, long-term growth, and the salary offered. While finalizing, we have to forego the other best offer. While deciding on a career, we have to consider options like prestige, impact and the work sector.

The way to calculate the opportunity cost is to subtract the value of the option from the value of the alternative that is foregone.

Opportunity Cost = Return on the best foregone alternative - Return on the chosen option.

Winning an argument often comes down to who can go the longest without contradicting themselves and keeping sound logic, not direct persuasion of the other party.

Using a single personal experience as the foundation of your argument or your big piece of evidence. 

For example, your phone may have broken right after you bought it, but you can’t use that to argue that those phones are not worth the purchase for others.

1. Fortune Telling: When one believes that the negative outcome is already a confirmed fact. The baseless assumptions are a reality inside the mind of a fortune teller. In most cases, things that seem to be a big worry have nothing to do with reality.
2. Mind Reading: Instead of focusing on probable bad situations, a mind reader creates unverified negative assumptions about people. These can be about people not respecting you, or about not getting acceptance from someone.

The basic psychology about visiting a fortune teller is that the mind is cognitively distorted and needs reassurance. When a fortune teller tells you that everything is going to be ok, the negative thoughts start to diminish.

Since we spend the majority of the time experiencing things from our own perspective, we struggle to imagine the perspective of others.

The curse of knowledge is a cognitive bias that makes it difficult for people to account for the fact that other people’s thoughts, beliefs, and views are different from their own.

You need to be conscious of the fact that people have different levels of knowledge than you.

• Ask for feedback from the people you are communicating with, in order to confirm that they understand what you are saying.
• Make sure that you explain the technical terms and concepts that you use as you are using it.

Adults use the fallacy more subtly.

"If you don't support the spending bill to develop better airplanes, our enemies will think we are weak and will attack us at some point, killing millions." The person offering this argument is using psychological pressure to get agreement. There is no apparent connection between "our enemies" and the conclusion that it will be in the country's best interest.
