Questions & Answers

Q: How does the social contagion effect influence share market movements?

The social contagion effect, or herding instinct, leads people to imitate the actions of others in the market. This behavior, even if the individuals are uncertain of the rationale behind it, can cause steep rises and falls in share prices. The fear of missing out or the desire to follow the crowd drives this pattern.

Q: How do cognitive biases impact financial decision-making?

Cognitive biases, such as confirmation bias and illusion of control, significantly affect financial decisions. Confirmation bias leads individuals to seek information that confirms their pre-existing beliefs or decisions. Illusion of control makes individuals feel that they have more influence or control over outcomes than they actually do. Both biases can lead to irrational choices and distort financial judgment.

Q: What is the sunk costs fallacy, and why is it more typical of adult humans than non-humans or children?

The sunk costs fallacy refers to the tendency to continue investing time, money, or resources into a project, even if it is no longer logical or beneficial. It is more common in adult humans because they are more prone to cognitive dissonance, a discomforting experience that arises when our actions contradict our beliefs. Adults have a developed sense of identity and investment in their decisions, making it harder for them to abandon a project they have already invested in.

Q: How does the endowment effect impact decision-making?

The endowment effect occurs when people place a higher value on an object they already possess compared to an equivalent object they don't own. This leads individuals to value possessions more and be resistant to parting with them. It can make negotiations, such as selling a house or a car, challenging due to the inflated value individuals place on their belongings.
