Putting ESP to the Test

Your Turn – Test Your Group the Way the Experts

Do!

What Are the Odds?

15 correct = 25% (same odds as guessing) 10 – 20 is average

Anything more than 25 correct considered “above chance” occurrence. Anyone telepathic? Replication?

How Do Psychologists Ask & Answer Questions?

Psychologists, like all scientists, use the scientific method to construct theories that

organize, summarize and simplify observations.

Theory

A theory is an explanation that integrates principles and organizes and predicts

behavior or events.

For example, low self-esteem contributes to depression.

ORPeople with telepathy can communicate

mind-to-mind.

Hypothesis

A hypothesis is a testable prediction, often prompted by a theory, to enable us

to accept, reject or revise the theory.

People with low self-esteem are apt to feel more depressed.

ORPeople with telepathy can “see” the suit of a card that another person is looking

at.

Research Observations

Research would require us to administer tests of self-esteem and depression.

Individuals who score low on a self-esteem test and high on a depression test would provide EVIDENCE for our hypothesis.

ORPeople who get more than 30% correct in a

card suit reading REPEATEDLY are EVIDENCE of our hypothesis.

Putting ESP to the Test

What parapsychology needs is REPRODUCIBLE phenomena AND a THEORY to explain it.

How can we TEST ESP?

An experiment differs from a staged demonstration.

In the lab, an experimenter CONTROLS what the “psychic” sees & hears. On stage it is the “psychic” in control.

The experiment

Testing ESP claims

Researching paranormal claims since 1957

“Parapsychology will achieve scientific acceptability only when it provides a positive theory with…independently replicable evidence. This is something it has yet to achieve after more than a century.”

Ray Hyman (2010)

Psychologist Daryl Bem

9 experiments, seemed to show precognition (2011)

When an erotic scene was about to appear on screen in 1 of 2 randomly selected positions, Cornell U participants guessed right 53.1% of the time (barely beat 50%).

Replication begins!
