About the Book
Science World By Tushar Sir
Looking Beyond Belief to Discover the Evidence
Superstitions are often passed from one generation to another without anyone stopping to ask how they began or whether they have a logical explanation.
Science Behind Superstitions – Part 3 continues this fascinating investigation by examining ten more familiar beliefs through science, psychology and rational observation. Instead of simply accepting or rejecting each belief, the book explores the circumstances that may have helped it develop.
Readers discover how coincidence, pattern recognition, fear, cultural traditions and cognitive biases can influence the way people understand everyday events.
Question. Observe. Understand.
TEN DIFFERENT TOPICS
Part 3 presents ten fresh beliefs without repeating the superstitions examined in the first volume.
WHAT DOES THE EVIDENCE SHOW?
Each chapter considers what can be observed or tested and distinguishes possible explanations from unsupported claims..
QUESTION THE CLAIM—NOT THE PERSON
The book encourages critical thinking while respecting the cultural background and personal experiences connected with traditional beliefs.
Part 3 encourages readers to ask three essential questions: What is the claim? What evidence supports it? Is there another reasonable explanation?
Why Can a Superstition Feel So Convincing?
A superstition may feel true even when there is no reliable evidence supporting it. This happens because the human brain naturally searches for patterns, remembers meaningful coincidences and learns from the people and traditions around it.
Understanding these mental processes helps us evaluate beliefs more fairly and accurately.
Pattern Recognition
The brain constantly searches for connections between events. Sometimes it identifies a relationship even when two events occurred together only by chance.
Confirmation Bias
People tend to notice and remember experiences that support an existing belief while overlooking the many occasions when the prediction did not come true.
Coincidence and Probability
Unusual coincidences are memorable. When a predicted event happens soon after a ritual or sign, it may appear connected even though coincidence provides a simpler explanation.
Social Learning
Beliefs are often learned from parents, relatives and communities. Repetition by trusted people can make an idea feel true before it has been independently examined.
The Need for Control
Protective rituals can reduce anxiety during uncertain situations. The feeling of comfort is real, but it does not necessarily mean that the ritual controls external events.
Scientific thinking encourages us to ask whether an explanation is supported by repeatable evidence or strengthened mainly by memory, expectation and coincidence.
INSIDE THE BOOK
From protective charms and animal behaviour to lucky gestures and travel rituals, Part 3 examines ten familiar superstitions. Each chapter explores how the belief may have originated and what science, psychology and evidence reveal about it.

03 — An Itchy Palm Predicts Money
An itchy palm is often interpreted as a sign of financial gain or loss. Science instead connects itching with dry skin, irritation, allergies and other physical causes.

10 — Knocking on Wood Prevents Misfortune
People often knock on wood after mentioning something positive. Explore the possible historical origins of this custom and how small protective rituals can temporarily reduce anxiety.
Part 3 does not simply label these beliefs as true or false. It asks what can be tested, what evidence shows and what practical or symbolic meaning may exist behind the tradition.
How Each Superstition Is Investigated
Every belief has a story. Rather than simply labelling a superstition as true or false, this book follows a clear and respectful method to understand how it began, why people continue to believe it and what reliable evidence reveals.
01. Identify the Belief
Each chapter begins with a clear explanation of the superstition, including how people commonly interpret and practise it.
02. Explore Its Possible Origin
The book considers the historical, cultural or practical circumstances that may have contributed to the development of the belief.
03. Examine the Scientific Explanation
Relevant ideas from biology, psychology, behaviour, the environment and everyday science are used to investigate the claim.
04. Evaluate the Evidence
The belief is compared with observation, logical reasoning and available evidence instead of being judged through fear or assumption.
05. Reach a Balanced Conclusion
Every chapter ends with a simple takeaway that respects cultural traditions while clearly separating symbolic meaning from scientifically supported facts.
Curiosity Is the Beginning of Scientific Thinking
When readers learn to question claims, observe carefully and look for evidence, they develop critical-thinking skills that can help them far beyond the subject of superstitions.
