10 "truth detective" skills
The Truth Detective book summary
A Survival Guide to an Age of Information Overflowing!
.
.
1. Set a "brain guard."
Don't just believe every graph or number seen at the first second! Always practice questioning where this source comes from, is it reliable, and does the presenter have any "covert intent"?
.
2. Be careful of "emotional spinning" information.
Deceptive news is often designed to make us angry or overjoyed. If you take any information and feel strongly moved by emotions, stop thinking. Don't rush to make a decision or share it.
.
3. Statistics go together, not always cause and effect.
Events A and B that occur at the same time do not necessarily mean that A is the cause of B (Correlation vs Causation). Don't rush to summarize the connection until you see clear evidence.
.
4. Know the "target."
The media often amplifies strange or exciting events to be so enormous that we forget to look at everyday truths or real statistics that are more likely to occur.
.
5. Find the "missing clue."
Often the truth is not in front of it, but in "what is not mentioned," such as choosing a biased sample, or choosing a show only of successful results. A good detective must also observe what is missing.
.
6. Don't be hypnotized by "huge numbers."
When we find a million or a billion digits, our brain always feels that it is great. The trick is to divide the average (i.e. divide by the population involved) to see the true proportion of the impact.
.
7. Beware of the "deceptive truth" trap.
Do not believe information simply because it "matches the heart" or "feels true" (self-affirmation bias or Confirmation Bias). Truth must be measured in facts, not just feelings.
.
8. Back out and look at the "big picture."
Our personal experience is a fraction of the world. Using "statistics" helps us to see macroscopic changes that we cannot experience on our own.
.
9. "Good Chart" has the power to change the world.
Raw numbers may be difficult to understand, but if they are arranged and presented as clear images, they can reveal hidden truths and create great changes.
.
10. "Curiosity" is the most powerful weapon.
The most important thing to be a truth detective is not mathematics versatility, but always to be open-minded, questioning, and ready to change perspective when new evidence is found that makes sense.
