Normative and positive statements | Basic economics concepts | AP Macroeconomics | Khan Academy
Summary
TLDRThis video script delves into the distinction between normative and positive statements, commonly found in economic and philosophical discussions. Normative statements reflect personal opinions or ethical beliefs about how the world should be, while positive statements are testable assertions about how the world is. The script provides examples to illustrate each type, such as the opinion-based nature of welfare fairness and the testable effects of tax policies on economic growth, highlighting the importance of distinguishing between what can be empirically verified and what is subjective judgment.
Takeaways
- 📚 Normative statements are based on opinions, ethics, or morals and reflect how the world should be.
- 🔍 Positive statements are testable and can be verified through empirical evidence or analysis, regardless of personal opinion.
- 🤔 The distinction between normative and positive statements is often made in economic and philosophical contexts.
- 🚫 Normative statements cannot be tested for truth or falsity; they are subjective and based on belief.
- 🔬 Positive statements can be empirically tested, even if the results may be inconclusive or subject to interpretation.
- 👎 The statement 'Paying people who aren't working, even though they could work, is wrong and unfair' is normative due to its judgment of right and wrong.
- 📈 The claim that welfare programs reduce the incentive to work is positive because it can be tested through comparative studies or surveys.
- 💼 The idea that raising taxes on the wealthy to fund government programs can affect economic growth is a positive statement, as it can be examined through simulations or case studies.
- 📉 Similarly, the statement that raising taxes on the wealthy slows economic growth is positive, as it can be empirically tested.
- 📋 The use of words like 'should' in a statement is a strong indicator that it is normative, as it suggests a prescriptive opinion rather than a testable fact.
- 🌐 Understanding the difference between normative and positive statements is crucial for clear communication and analysis in economics and policy-making.
Q & A

📚 Understanding Normative and Positive Statements
This paragraph introduces the distinction between normative and positive statements, often used in economic and philosophical discussions. Normative statements are based on opinions, ethics, or morals, reflecting how the world should be, while positive statements are testable claims that can be verified or falsified. The video aims to classify various economic statements into these two categories.
🤔 Classifying 'Paying People Not Working' as Normative
The first example statement, 'Paying people who aren't working, even though they could work, is wrong and unfair,' is identified as a normative statement. This is because it expresses an opinion on what is right or wrong, which cannot be empirically tested but is a matter of personal belief.
🔍 Testing the Impact of Welfare Programs Positively
The second statement, 'Programs like welfare reduce the incentive for people to work,' is classified as a positive statement. It suggests a hypothesis that can be tested through empirical methods, such as instituting a welfare program on a small scale and comparing it to a similar situation without such a program to observe its effect on work incentives.
📈 Analyzing the Economic Effects of Taxing the Wealthy
The statement 'Raising taxes on the wealthy to pay for government programs grows the economy' is also considered positive. It proposes a testable claim about the economic impact of a specific policy. The video suggests that one could run simulations or examine case studies to determine the validity of this statement.
🛑 The Testable Assertion of Taxing Wealth and Economic Growth
Similarly, the statement 'Raising taxes on the wealthy slows economic growth' is a positive statement. It can be empirically tested by comparing economic growth rates in countries that have implemented such policies with those that have not, using computer simulations or historical data.
🏛️ The Normative Call for Taxing the Wealthy to Help the Poor
The final example, 'The government should raise taxes on the wealthy to pay for helping the poor,' is a normative statement. The use of the word 'should' indicates a prescriptive opinion rather than a testable fact, emphasizing the ethical or moral stance of the speaker.

Highlights
The video discusses the distinction between normative and positive statements, often used in economic and philosophical contexts.
A normative statement reflects personal opinion or ethics about how the world should be.
Positive statements are testable and do not necessarily have to be true.
The video will classify economic statements into normative or positive categories.
Statement 'Paying people who aren't working is wrong and unfair' is identified as a normative statement.
Normative statements cannot be tested and are based on belief.
Welfare programs' impact on work incentives is a testable positive statement.
The statement 'Raising taxes on the wealthy to pay for government programs grows the economy' is testable and thus positive.
Testing a statement involves simulations, case studies, or surveys to determine its validity.
The statement 'Raising taxes on the wealthy slows economic growth' is also a positive statement due to its testability.
The use of words like 'should' indicates a normative statement, as in 'The government should raise taxes on the wealthy to help the poor'.
Normative statements are based on ethical or moral beliefs rather than testable facts.
The video emphasizes the importance of distinguishing between testable and non-testable statements in economics.
Understanding the difference helps in evaluating the credibility and applicability of economic theories and policies.
The video concludes by reinforcing the definitions of normative and positive statements and their implications.
Normative statements are subjective and cannot be empirically verified, unlike positive statements.
Transcripts
- [Instructor] What we're going to do in this video
is discuss the difference between normative statements
and positive statements, and you'll see these words used
usually in an economic context,
sometimes a philosophical one.
A normative statement is one that really is a matter
of opinion, maybe a matter of ethics,
something that someone thinks is how the world should be.
While a positive statement is something that,
it doesn't necessarily have to be true
but it's something that can be tested.
So what we're going to do in this video
is look at a bunch of statements around economics
and think about whether they would be classified
as normative statements, things that are opinions,
that are a matter of ethics or morals,
or whether they are positive statements,
things that can be tested.
So let's look at our first statement.
This says, "Paying people who aren't working,
"even though they could work, is wrong and unfair."
So regardless of whether or not you agree
with this statement, is it a normative statement
or a positive statement?
Well the fact that someone's saying it's wrong
and it's unfair, this is pretty clearly a matter of opinion
so this would be a normative statement.
You can't test whether this is wrong or unfair,
you would just have to believe that it is wrong and unfair.
Now let's look at another statement.
Programs like welfare reduce the incentive
for people to work.
Is this a normative statement or a positive statement?
Well it might feel a little normative,
it might feel like this is an opinion,
but it actually can be tested.
You could institute some welfare program on some small scale
and compare it to a comparable place
where there isn't a welfare program and see what it does
for incentives to work, you survey people,
you see how many people work in one situation or another.
It might be a false statement, it might be a true statement,
but either way, it actually can be tested,
so this would be a positive statement
so I'll put it in this category right over here,
this is a positive, positive statement.
Alright, let's look at another one.
This say, "Raising taxes on the wealthy to pay
"for government programs grows the economy."
Is that a normative statement or a positive statement?
Well once again, this can be tested.
It might be true, it might be false, maybe your test
is even inconclusive, but it can be tested,
you could try to run a simulation, you could look
at case studies of countries that did do this
and see what happens to their economy
versus ones that didn't do it.
And so this is, even though it looks like something
that someone who favors raising taxes on the wealthy
maybe out of fairness arguments, something that they would
say, this statement itself is not normative,
the statement can be tested,
so this is a positive statement.
A good giveaway for normative statement,
if it said something like it is fair to raise taxes
on the wealthy to pay for government programs,
that would have been a normative statement
or we should do this, that would have been a normative
statement but here, this is something that's testable.
Now the next statement, "Raising taxes on the wealthy
"slows economic growth."
Is that a normative statement or a positive statement?
Well, once again, this might feel like someone
who is against raising taxes, who think it's unfair
to raise taxes on the wealthy, something that they would say
but the statement itself can actually be tested.
So this is also a positive statement,
even though in some ways it's the opposite statement
as the one that we just did.
Because once again, we could look at countries that did this
and countries that didn't do this,
we could run a computer simulation to try to understand
whether this statement is true.
Let's do one last statement.
This says, "The government should raise taxes
"on the wealthy to pay for helping the poor."
Is this normative or positive?
Well in this situation,
the word should is a pretty big giveaway,
should, or it's fair or unfair, this is someone's opinion,
it's not something that's testable,
you can't test whether this statement is right or wrong,
it's based on, do you believe ethically, morally,
that this is true?
And so this is a normative statement,
so I'll put it in the normative column.
So big picture, these words normative and positive,
these are fancy words but all they mean is normative
is a matter of morals or opinion and can't really be tested
while a positive statement, whether they're right or wrong
or whether you agree or disagree with them,
these are things that in theory could be tested.
