Keywords

💡Critical Thinking

Critical thinking is the ability to analyze and evaluate information objectively. In the video, it is emphasized as a vital skill for understanding complex problems and making informed decisions. The script mentions that critical thinking is not just for winning arguments but for engaging with the world in a thoughtful and analytical manner. It is used to navigate through various life situations, such as those encountered in relationships, work, and school.

💡Scientific Literacy

Scientific literacy refers to the knowledge and understanding of scientific concepts and processes. The video script highlights that it's not just about knowing facts but about refining one's thinking to be more precise and making decisions based on evidence rather than emotions or authority. It's portrayed as a tool for enhancing critical thinking skills.

💡Observation

Observation is the act of noticing and perceiving information through the senses or with the aid of instruments. In the context of the video, observation is the first step in the scientific method and is crucial for gathering data about the world around us. The script gives examples of how observation can be both casual, like noticing the environment, or more systematic, like using a thermometer to measure temperature.

💡Hypothesis

A hypothesis is a proposed explanation for a phenomenon, made on the basis of limited evidence as a starting point for further investigation. The video script explains that a hypothesis is a tentative guess that needs to be tested through experiments to determine its validity. It's depicted as an essential part of the scientific method and critical thinking process.

💡Experiment

An experiment is a procedure carried out to support, refute, or validate a hypothesis. The video script describes experiments as actions taken to test the truth of a hypothesis, which can range from simple measurements to complex clinical trials. The script uses the example of testing the temperature outside to illustrate how an experiment can confirm or refute a hypothesis.

💡Data Analysis

Data analysis involves examining, cleaning, transforming, and modeling data to extract useful information, draw conclusions, or support decision-making. In the video, data analysis is the process of evaluating the results of experiments to determine whether to accept or reject a hypothesis. It's a critical step in the scientific method that helps in making evidence-based decisions.

💡Scientific Method

The scientific method is a systematic approach to research that involves making observations, formulating hypotheses, and conducting experiments to test these hypotheses. The video script outlines the scientific method as a series of steps that form the foundation of critical thinking and problem-solving. It is presented as a practical tool that can be applied in everyday life to solve problems and make informed decisions.

💡Probabilities

Probabilities refer to the likelihood or chance of something happening. The video script clarifies that science deals in probabilities rather than absolute truths. This concept is important because it acknowledges the limitations of scientific knowledge and the potential for exceptions to any rule or law.

💡Ultimate Truths

Ultimate truths are statements that are considered to be absolutely true without exception. The video script contrasts the search for ultimate truths with the scientific approach, which is based on probabilities and evidence. It suggests that the pursuit of ultimate truths is more aligned with faith and philosophy rather than science.

💡Practicality

Practicality refers to the quality of being practical or useful in a real-world context. The video script argues that while science may not provide access to absolute truths, its methods are extremely practical for everyday problem-solving. It encourages the application of the scientific method to enhance critical thinking and decision-making in daily life.

Transcripts

you

critical thinking skills are very

important for getting along in life they

allow you to analyze problems or

situations you find yourself involved in

that don't always have an easy or

obvious answer we all run into problems

in relationships work school etc

wouldn't it be easier if we could

understand why things were happening

around us and more easily see what we

could do about them that's what critical

thinking is all about it's not just for

winning arguments a theme I'm going to

return to again and again is that

science is not just for scientists and

it's not just about knowing obscure

facts like how hot is the Sun or what's

the Latin name for a black bear

scientific literacy is about fine-tuning

your thinking so it's more precise and

making decisions based more on facts and

direct observation instead of how you

feel emotionally or because some

authority told you to do something

science is very helpful in critical

thinking but let's talk about science

for just a second before we get into

this a common mistake that people make

about science is that it's trying to

find ultimate truths in other words

discover laws or facts that have no

exceptions ever and are always true

under any condition that would be an

ultimate truth science does not deal in

that kind of truth it deals in

probabilities in fact when you get into

discussing or studying ultimate truths

you're in the realm of faith and

philosophy not science at all and this

is why the endless debates about science

versus religion are never going to be

fully resolved it's oil and water

despite our technology and advances were

still very limited in how we can

perceive the universe and in how we

think the reason that I say that it's

not possible for us as human beings to

discover ultimate truths is because

there could always be and usually are

exceptions to the rules and laws that

scientists discover just because we

can't perceive or haven't discovered in

an exception to a rule doesn't mean that

rule is absolutely true there's always a

chance that the rule could be wrong so

if you have the idea that science is

about absolutes in anything please erase

that idea

now having stated that science is

limited I want to also say that science

is extremely practical in anyone's

day-to-day life it may not have access

to absolute truths but the methods and

rules of science are among the best that

we do have to figure things out there's

a thing called the scientific method

which really just means the steps any

scientist takes to solve problems or

discover new things the good news is

that just because it has the word

scientific in it doesn't mean that it's

hard to understand or use in fact you

most likely already use the scientific

method all the time but like any skill

it's something that can be greatly

improved through conscientious practice

scientific method can be described in

different ways and some people include

slightly different steps but basically

it comes down to these one make

observations looking is the first and

most important step whether it's

noticing something odd or interesting or

whether you're confronted with a problem

of some kind the first thing you do is

observe observation doesn't take place

just because of something unusual or odd

you can easily observe what's going on

around you anytime

for example stop watching this for a

moment and look up at the space around

you notice something you may never have

noticed before or see if there was

anything in the environment around you

that is different from what you remember

the last time you looked around

that's observation in science we use the

word observation rather than looking

because observing is not just done with

the eyes visual observation is important

but it can also include any of your

senses walking into a room and smelling

something bad is observation hearing a

ringing sound coming from a machine

we're feeling warm air coming off a hot

pad are perfectly valid observations

it also can involve using instruments or

measuring devices it's kind of hard to

see with the naked eye that something is

five point four nine eight centimeters

wide having a measuring device helps in

the accuracy of the observation using a

telescope to observe a distant planet or

a microscope to observe cellular

behavior is the only way we can even be

aware of these

who knows what else is out there that we

don't know about because we have no way

of observing it observing by the way is

something that you do on purpose it's

not passive you can't observe something

when you're putting up some mental

picture of what you've always seen there

every single day instead of foreseeing

what is really there right now in this

moment people do this all the time it's

not unusual at all for someone to be

looking right into an intersection and

not see the person on a motorcycle 20

feet away they aren't really observing

what's going on in front of them instead

they're seeing the same thing they

always see when they cross this same

intersection on their way home from work

every day their mind is on other things

and it's one reason people miss things

that are perfectly obvious to other

people around them observation is a

skill you can practice all by itself and

it should be practiced every day to

propose a hypothesis a hypothesis is an

idea or a proposition that explains an

observation it's not necessarily true

but it's a starting point it's basically

a guess as to why a particular

observation is the way it is it's now up

to the person who made the hypothesis to

find evidence to prove whether it's true

or not in real life

outside of science many people will

guess or dream up explanations or

answers and then stop right there

they'll assume that what they came up

with is true because it's the best

answer they could come up with based on

the information available to them at the

time until you have some proof and have

verified the hypothesis is correct it's

just as likely that it's not true and

you could end up making a really big

mistake so it's very important to

realize that a hypothesis is not the end

of critical thinking it's just the

beginning an example of a hypothesis you

could propose would be something about

the weather

here we are in the middle of December

you're inside and you see that it's

crystal clear outside the sun is shining

brightly with no clouds there appears to

be a slight breeze blowing

you hate having to bundle up every time

you want to go outside so you think to

yourself that perhaps today it's not

really so cold out how could it be when

it's so clear and beautiful you propose

a hypothesis the temperature outside is

tolerable and you won't require you to

multi layer two shirts a sweater and

your parka just to get out to your car

so you can drive to work this could just

be wishful thinking so before you act on

it you first have to test that

hypothesis three design and perform an

experiment to test the hypothesis an

experiment is simply anything that is

done to test whether hypothesis proves

out to be true or false experiments can

be simple like just taking a measurement

of something to see if it's the amount

you think it is they can also be very

complicated such as injecting a new

medicine into thousands of people and

carefully monitoring the results as well

as monitoring injections of a placebo a

fake medicine into a similar group of

people to see what happens to them too

by comparing the results of the real

medicine to the fake medicine you can

test its effectiveness the most

important thing about experimentation is

testing your hypothesis in such a way as

to actually prove out whether it's true

or false depending on the circumstances

it may take many experiments before you

can conclude for sure that your

hypothesis is valid in the case of our

hypothesis about the temperature outside

there are a couple of experiments you

could perform to test this out look at a

thermometer on the window in doing so

you see that it shows the temperature

outside is five degrees okay that is one

indication that it is not so warm

outside it's not necessarily conclusive

evidence yet but it's a start the

thermometer could be off because it

could be broken and also it may only be

measuring the temperature in one

specific location where there could be a

cold pocket open the window and stick

your head outside the freezing cold

temperature assaults your face and the

slight breeze stings your skin you

quickly close the window you determine

at this point that your experiment is

over one last point on experimentation

to find out whether it's

outside you could always just consult

Google or The Weather Channel but that

is not really an experiment things on

the internet or on the TV or radio come

from people when you google something

you're basically asking someone else for

their opinion or their ideas no matter

who is telling you what there's always a

chance that could be wrong they may be

able to point you in a direction or help

you with an experiment but that's not

the same thing as accepting their

opinions or ideas as facts one of the

most common mistakes in logic and

critical thinking is to take someone

else's opinions or facts as true without

verifying it yourself first for analyze

your data determine whether to accept or

reject the hypothesis now that you have

the results of your experiments you use

that to determine whether your

hypothesis was correct in our simple

case we have the following results

temperature reads 5 degrees outside

physical tests of the air and

temperature indicated that it was frigid

and very uncomfortable the hypothesis

that it is warm and tolerable outside

has been proven false it is in fact

freezing and you decide that you're not

going out without bundling up first five

if necessary propose and test a new

hypothesis in this case there is no need

to proceed with further hypotheses as

the one we came up with was proven wrong

at the same time we concluded that

bundling up would handle our aversion to

the freezing weather there are many

other instances where you may make one

hypothesis test it out and it doesn't

turn out to be true and then you need to

come up with another one let's say

you're working on fixing a broken air

conditioner you don't know what the

problem is exactly but you see that a

pipe is sticking out that doesn't look

like it should

so you experiment with putting it back

in place that seemed to be a good idea

but the air conditioner still doesn't

work after you fix the pipe so you look

some more and see that it's not plugged

in you formulate a new hypothesis that

it may not be working because it needs

electricity you plug it in and voila it

turns on and operates smoothly

perhaps the pipe and the electricity

both needed to be fixed before it would

operate the bottom line is that by

observing experimenting and reevaluating

the information and further

experimenting you were able to solve the

problem that is what the scientific

method is for following these steps are

the heart of critical thinking

chances are you already are doing these

steps many times every single day but my

knowing these steps and going over them

yourself you can be more certain about

what you're doing you can also catch

yourself if you miss a step or find

yourself stuck the solution to almost

any problem you will encounter in life

is to observe analyze experiment and

reevaluate based on what you find until

you come up with a solution practice

practice practice using the steps of the

scientific method and see what results

you get every single discovery in our

history every leap forward in science or

technology or anything else was made

using these steps they are the basis of

all the rests of the critical thinking

skills you can learn learn them well and

may your life and thinking never be the

same again

just for fun and to give you an idea of

how this can be practiced in real life

here are some practical exercises you

can do one the next time you go into a

spacer room you're very familiar with

look around the room and observe it as

though you had never seen it before

see if you can find at least three

things about the space that you have

never noticed before to recall some

example from your experience where a

problem was solved using scientific

method break down the steps so you can

see what hypothesis you formed and how

you tested it and then proved it to be

correct 3 see if you can recall a time

that you or someone you know came up

with a hypothesis but then did not test

it out before acting on it what was the

result what could they have done as an

experiment to test the hypothesis for

the next time you encounter a problem in

life form a hypothesis about what the

source of the problem might be perform

some kind of test or experiment to see

if your hypothesis is actually valid

only after you have proven that the

hypothesis is correct

come up with a solution notice to

yourself what might have happened if you

had not verified your hypothesis before

acting I am very interested in what

results you get from these exercises

please leave me any comments if you have

any feedback on this they may seem

simple but these are very workable thank

you for watching
