Q & A
What is the main theme of the video script?
-The main theme of the video script is the importance of critical thinking skills in daily life and how science, particularly the scientific method, can be applied to enhance these skills.
Why are critical thinking skills important according to the script?
-Critical thinking skills are important because they allow individuals to analyze problems or situations that don't have easy or obvious answers, helping them to understand why things are happening and what they can do about them.
What is the common misconception about science mentioned in the script?
-The common misconception mentioned in the script is that science is about finding ultimate truths, which are laws or facts that have no exceptions and are always true under any condition.
How does the script differentiate between science and faith/philosophy?
-The script differentiates science from faith and philosophy by stating that science deals in probabilities, while discussing ultimate truths is more in the realm of faith and philosophy.
What is the scientific method according to the script?
-The scientific method, as described in the script, is a series of steps scientists take to solve problems or discover new things, which includes making observations, proposing a hypothesis, designing and performing experiments, analyzing data, and reevaluating based on the findings.
What is the first step in the scientific method as outlined in the script?
-The first step in the scientific method is making observations, which involves noticing something odd or interesting or being confronted with a problem.
Why is it important to not just accept someone else's opinions or facts as true without verifying them?
-It is important not to accept someone else's opinions or facts as true without verifying them because there is always a chance that they could be wrong, and accepting them without verification can lead to mistakes.
What is a hypothesis in the context of the scientific method?
-A hypothesis is an idea or proposition that explains an observation. It is a starting point and a guess as to why a particular observation is the way it is, which needs to be tested for evidence to prove its validity.
How does the script suggest testing a hypothesis?
-The script suggests testing a hypothesis by designing and performing experiments that can prove whether the hypothesis is true or false, and analyzing the data to determine whether to accept or reject the hypothesis.
What are some practical exercises suggested in the script to practice critical thinking?
-The script suggests practical exercises such as observing a familiar space as if seeing it for the first time, recalling a problem solved using the scientific method, and forming and testing hypotheses in everyday life situations.

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
