Thinking that a plane crash is more likely than a car crash because you can easily remember dramatic images of plane crashes on TV is an example of what cognitive shortcut?

Answers

Answer:The availability heuristic

Explanation: Sometimes when we need to make decisions and we don't have much facts available to us, we may use shorts cuts. The availability heuristic occurs when we depend on the similar examples that comes to mind in order to make our conclusion. The more situations that keep popping to our mind the more likely to judge that they are more prevalent and we tend to believe that there is high chance of them to keep happening in the future because we believe they are more frequent due to the fact that we have many examples of those situations coming up in our mind.

Final answer:

Overestimating the likelihood of plane crashes over car crashes due to memorable media coverage is an example of the availability heuristic, a cognitive shortcut where judgments are based on memory ease, often leading to skewed perceptions of risk.

Explanation:

Thinking that a plane crash is more likely than a car crash because you can easily remember dramatic images of plane crashes on TV is an example of the availability heuristic. This cognitive shortcut involves judging the frequency or likelihood of an event based on how easily examples of the event can be recalled from memory.

In the case of plane and car crashes, dramatic and well-publicized events such as plane crashes can be more easily remembered, leading individuals to overestimate their frequency compared to more common but less sensational events, such as car crashes.

The availability heuristic can lead to errors in judgment about risks and frequencies of events. For example, people may overestimate the probability of dying from acts of terrorism when, statistically, it is much less likely than dying from chronic diseases or car accidents. Such biases can have significant implications on individual and societal behavior and decision-making.

A. he held this would allow the population to thin itself out naturally
B. he felt this would create more jobs for medical personnel and morticians
C. he was mentally ill
D. he was a forerunner to Hitler

Answers

Answer:A. he held this would allow the population to thin itself out naturally

Explanation:

Thomas Malthus's theory was concerned with the rate of population growth. He the established the Malthusian theory of population growth which states that population growth occurs exponentially, whilst the production of food increases linearly. Exponentially means it increases faster and faster especially as birth rates also increases. Linear increase of food production means it goes through stages and can only increase at a given point.

As a resulf of this , it likely that population will grow up to a point where the available resources are less than the population itself , it will out grow the resources.

So he looked at want can be done to reduce this potential effect of poulation growth and he determined types of checks.

Preventive checks things are things that people can do voluntarily such as delaying getting married in which he supported moral restraint as a religious person himself.

He also determined positive checks which may help shorten the lifespan such as disease,famine ,warfare and poor living. So to him these catastrophic events may assist in reducing the increase of population by shortening the life span, naturally decreasing the population.
