Critical Thinking about Sciencein The Media

Let’s Academicize!

Calm Islands of Truth Seeking in Stormy Seas with Oceans of

EmotionSchools - Teach true statements Learn skills to find true statements Research to find new true statements

WHAT IS KNOWLEDGE? KNOWLEDGE = Justified True Belief

(at 03:00) ”What was it all for?” ”Knowledge” ”Also, to show what was possible” http://www.esa.int/Our_Activities/Space_Science/Rosetta/Rosetta_the_ambition_to_turn_science_fiction_into_science_fact

Politics is NOT Science

Politicians make policies on consensus versus Science checks the evidence and logic of arguments

There IS a difference

Majority Wins Evidence & Logic Valued

I’m Right!

I’m Right!

I’m Right!

-----------------------------

So, VOTE! VOTE! VOTE! for ME! ME! MEEEEEE!

FOR:

Scientific Evidence 1?

Scientific Evidence 2?

-----------------------------

Logical Conclusion 1?

AGAINST:

Scientific Evidence 3?

Scientific Evidence 4?

-----------------------------

Logical Conclusion 2?

Business PPPs are NOT Scientific Presentations

information poor to information rich

Businesses sell products to make money versus Science checks the evidence and logic of arguments

There IS a difference

Death by Business PPPs

Life by Science PPPs

I’m Right!

I’m Right!

I’m Right!

-----------------------------

So, BUY! BUY! BUY!

FOR:

Scientific Evidence 1?

Scientific Evidence 2?

Information Rich ”Beautiful Evidence” in Science PPPs

• Like a science paper or newspaper

• high information content

• Texts, graphs, images, data - mixed together

• for & against arguments on same slide

• NO bullit points / but whole sentences

• Oops! ;-)

Critical ThinkingIs It True?

( Being Skeptical ... then using ... “The Method” )

Don’t be a sponge .... pan for the gold nuggets!

Critical Thinking: Why bother?

Would you rather be a mental puppet of who ever you happen to encounter?OR

Have a method to decide which opinions to believe or reject!

Critical Thinking

1. Skeptical – ”Is it true?”

2. Calculate – Check the facts ... AND ... check the argument

Critical thinking about Media Science news stories

Critical Thinking Question:

Are the premises of science news stories true?

If a cat has all white fur then it is a white cat.

The cat has all black fur.

-------------------------------------------------------

Therefore it is a white cat.

“When the facts change, I change my mind. What do you do, sir?” – attributed to John Maynard Keynes (economist)

A common human argument

check the facts not the feelings

check the evidence not the emotions

What we often do with new facts we don’t like.

A rational mind changes its conclusions when new facts and arguments arise.

”... Students should develop crtitcal thoughts regarding their own results, other’s arguments and different information sources ... critical of information and arguments which students meet in various sources and discussions to do with science in society with connections to biology/chemistry/physics...” - Extract form the Swedish Primary School curriculum in science (2011).

Critical Thinking for schools

Critical Thinking: more basics

Deductive arguments

P1 All men are mortal.P2 Socrates is a man.____C Socrates is mortal.

Inductive arguments

P1 If Socrates is a man, then he is most likely mortal.P2 Socrates is a man._________C Socrates is probably mortal

Plausible arguments

P1 Ms A is a genuine expert about man's mortality.P2 Ms A proposes that Socrates is mortal.P3 Socrates is a man.P4 That ”Socrates is mortal” is consistent with what other experts propose. P5 “Socrates is mortal” is consistent with the available evidence.________C ”Socrates is mortal” can be accepted as a plausible argument.

Critical Thinking What is a “good” argument?

Socrates 469 BC – 399 BC Athena – Goddess of Wisdom

A “good” argument has all true premises.

Critical Thinking: The 4 basic logical “forms” of an argument

Critical Thinking for beginners

The Law of Similarity : appearance = reality

If it looks like a lion, it is a lion...Run! ...or you will be lunch!

If we watch a hurricane on TV ... worry about storms! If read about a flood in NY ... the seas are rising!

Why We Worry (Lion-

Worriers survived and reproduced)

Human ”GroupThink” is an Evolutionary Stable Strategy (stay in the group, run with the herd ... and you

survive and reproduce)

Are we are running with the herd ... again ... ...& stampeding over the cliff of missing scientific

evidence?

The Carta Marina by Olaus Magnus (1490-1557) is the earliest detailed map of the Nordic countries.

”Here there be Dragons” – when emotion replaces evidence in Science

The Conjuror, by Hieronymus Bosch, painted 1475-1480 to convey concern for human gullibility.”Bosch seems to admonish his viewers that the world is full of deceivers we should not trust

yet who succeed in taking advantage of us with all kinds of tricks.”http://suite101.com/article/meaning_in_the_conjurers-a162088

Watch the peas under the Media Science shell game

History of popular folly (1841) by Scottish journalist Charles MacKay, he proposed that crowds of people often behave irrationally

Scares in History

economic bubbles (tulip mania), alchemy, crusades, witch-hunts, prophecies, fortune-telling, magnetisers (influence of imagination in curing disease), haunted houses, popular follies of great cities etc.

“Men, it has been well said, think in herds; it will be seen that they go mad in herds, while they only recover their senses slowly, and one by one.” – Charles McKay (1841)

Has all this happened many times before?

NEW SCARE

Defining parts of a Scare* A new type of threat.* Something anyone might be exposed to.* A large undefined uncertainty of effects.* Society's response is out of all proportion to the reality of the threat.

Common stages of a Scare* Appearance of widely accepted scientific evidence* Obsessive media coverage* Massive response from politicians.* New laws and restrictions enacted.* Social damage - fear/hysteria//panic* Economic damage - $M/$B/$T spent* Scientific evidence & reasoning then accepted as fundamentally flawed.* Fear subsides and money all wasted.* New & different scare begins again.

”... interests behind behind views from different sources...”

WHY? -A BIT OF HISTORY Snake Oil Salesmen still alive &

well; bigger & ”better” 100 years later in the 21st Century

So ... check the evidence & check the arguments when the health-energy-environment-technology snake oil salesmen & snake oil saleswomen visit your neighbourhood ... today.

Or, are these ”salespersons” just … caring & misinformed … or ”morally superior” … or … GroupThinkers or …???

”Take a knee”: Natural dangers are real but fear about the world is a choice.

Opposing viewpoints - seek them out! Prepare to be unpopular in following the thin red line of truth

Ask probing questions Real Science doesn’t follow fashionable trends or popularity ...

it follows the scientific method and logical arguments.

The Paling Risk Perspective

Risks around 1 in a million to 1 in 10,000 that have odds in this green "Home Base Zone" should certainly not be ignored but should not be singled out for alarmist media headlines.

An even better future world – Emotions versus …… Evidence: everybody is getting richer

An “Evidence-Based Science” trend to a bright happy future society

More of everything:• More energy use• More consumption• Cleaner environment • More people• More live in cities• More wilderness• Healthier people• Happier people• Longer lives

(Check the evidence ...... not the emotion :-) (Check the facts ...... not the fiction :-)

Other CO2 -Global Warming inconvenient

truths

Sea level rises slowing

Deserts greening & Earth too

Lower atmosphere cooling

Hurricanes decreasing

No climate crop losses

Temps go down as CO2 goes up

science textbooks say, but ...

"Nothing in biology makes sense, except in the light of evolution." - Theodosius Dobzhansky 1973

Why?

Are Treelines ”moving uphill” because of rising temperatures? ... or changes in rainfall, CO2 concs, biologically-available nitrogen (and other nutrients), and

even winds?
