1
00:00:00,555 --> 00:00:01,658
Is it a fact

2
00:00:01,658 --> 00:00:02,848
or is it an opinion?

3
00:00:03,198 --> 00:00:04,279
Does it matter?

4
00:00:04,400 --> 00:00:05,421
Yes.

5
00:00:05,421 --> 00:00:06,433
Both are important.

6
00:00:06,693 --> 00:00:09,501
But knowing how to distinguish
between fact and opinion

7
00:00:09,501 --> 00:00:12,751
can help us to better understand
what we read and hear,

8
00:00:12,751 --> 00:00:14,665
and how we form our own opinions.

9
00:00:15,088 --> 00:00:16,318
Let's take a look.

10
00:00:17,356 --> 00:00:19,970
A fact is a statement 
that can be proven to be true.

11
00:00:20,472 --> 00:00:21,726
Facts are objetive,

12
00:00:21,726 --> 00:00:25,201
which means they are not influenced
by what someone thinks or believes.

13
00:00:25,450 --> 00:00:28,303
A fact is indisputable
and cannot be changed.

14
00:00:28,624 --> 00:00:30,878
Here are some key questions
to identify facts.

15
00:00:31,294 --> 00:00:35,073
1. Can it be measured or confirmed
with calculations or data?

16
00:00:36,383 --> 00:00:39,395
For example, two plus two equals four.

17
00:00:39,680 --> 00:00:42,929
We can add the numbers
and demostrate that this stament is true.

18
00:00:43,533 --> 00:00:46,804
2. Can it be observed? 
Can we see it happen?

19
00:00:48,607 --> 00:00:52,133
For instance, 99% of people
cannot lick ther elbow.

20
00:00:53,183 --> 00:00:54,201
This is true.

21
00:00:54,201 --> 00:00:55,989
This is a fact that can be observed.

22
00:00:56,349 --> 00:00:57,556
Research has determined

23
00:00:57,556 --> 00:01:01,347
that only one out of 100 people
can successfully complete this task.

24
00:01:02,214 --> 00:01:05,273
3. Can it be verified by primary sources,

25
00:01:06,052 --> 00:01:09,921
such as research, photographs,
newspapers and artifacts?

26
00:01:10,314 --> 00:01:11,453
Here is an example.

27
00:01:12,062 --> 00:01:14,080
Nintendo was started in 1889.

28
00:01:14,289 --> 00:01:17,527
This is a fact, because it could
be verified with many sources.

29
00:01:17,657 --> 00:01:20,485
A man named Fusajiro Yamauchi from Japan

30
00:01:20,485 --> 00:01:23,786
founded Nintendo
as a playing card company in 1889,

31
00:01:23,786 --> 00:01:26,766
and now it is one of the largest
gaming companies in the world.

32
00:01:27,178 --> 00:01:29,054
Now let's move on to opinion,

33
00:01:29,054 --> 00:01:31,644
which can sometimes be a little trickier.

34
00:01:31,986 --> 00:01:34,369
An opinion is a statement
of belief or judgement.

35
00:01:34,786 --> 00:01:37,682
Opinions express
what someone thinks or feels.

36
00:01:37,682 --> 00:01:39,335
An opinion can change.

37
00:01:39,558 --> 00:01:41,075
Let's look at some examples.

38
00:01:41,570 --> 00:01:43,421
Ice cream is delicious.

39
00:01:43,771 --> 00:01:46,108
Many people believe this, 
but some people don't.

40
00:01:46,378 --> 00:01:48,747
It is a judgement, 
and therefore an opinion.

41
00:01:49,424 --> 00:01:51,492
When we evaluate something or somebody

42
00:01:51,492 --> 00:01:56,200
we often use adjectives such as
important, beautiful, fun or difficult.

43
00:01:56,753 --> 00:01:58,901
An adjective that allows us
to judge something

44
00:01:58,901 --> 00:02:01,198
is a clue that a statement is an opinion.

45
00:02:01,935 --> 00:02:05,189
Another signal word for opinions
is the word "should".

46
00:02:05,380 --> 00:02:06,408
Here is an example.

47
00:02:06,671 --> 00:02:08,915
Everyone should learn
more than one language.

48
00:02:09,252 --> 00:02:12,567
While there may be many good reasons
to learn more than one language,

49
00:02:12,750 --> 00:02:15,811
not everyone would agree
about the personal value of doing so.

50
00:02:16,624 --> 00:02:18,676
Political views are opinions.

51
00:02:18,935 --> 00:02:22,017
Different people will have different ideas
about what society's problems are

52
00:02:22,017 --> 00:02:23,770
and how to best address them.

53
00:02:23,886 --> 00:02:26,350
Since opinion can´t 
be proven or disproven,

54
00:02:26,350 --> 00:02:27,977
there is no right or wrong answer:

55
00:02:27,977 --> 00:02:29,693
just different viewpoints.

56
00:02:30,109 --> 00:02:32,872
While opinions may be supported
by facts and evidence,

57
00:02:33,060 --> 00:02:35,877
the issue we care about
may still be up for debate.

58
00:02:36,277 --> 00:02:37,371
For example, I could say

59
00:02:37,371 --> 00:02:40,246
that going to school year round 
is better for students.

60
00:02:40,876 --> 00:02:43,742
Now there are reasons
to support this viewpoint,

61
00:02:43,742 --> 00:02:45,959
some might argue
that a shorter vacation period

62
00:02:45,959 --> 00:02:48,390
would prevent students
from forgetting what they learnt,

63
00:02:48,390 --> 00:02:51,287
or say that students often
get bored over the summer,

64
00:02:51,287 --> 00:02:54,635
or that other countries around the world
use a year-round system.

65
00:02:55,283 --> 00:02:58,266
However, we cannot prove
that the statement is true.

66
00:02:58,489 --> 00:03:01,729
There are many reasons to think
that a 10 month calendar is better.

67
00:03:01,828 --> 00:03:04,375
You could argue that students
need an extended break

68
00:03:04,375 --> 00:03:08,051
and they should be allowed to participate
in camps or other summer activities,

69
00:03:08,051 --> 00:03:09,522
or that a lack of air conditioning

70
00:03:09,522 --> 00:03:12,726
means they shouldn't be inside
a school building in the summer.

71
00:03:13,386 --> 00:03:15,100
If we look back at the statement,

72
00:03:15,100 --> 00:03:17,994
we can also identify
another signal word for opinion:

73
00:03:18,503 --> 00:03:19,916
the word "better".

74
00:03:20,276 --> 00:03:21,806
When we're comparing different things

75
00:03:21,806 --> 00:03:24,766
or we see words like "greatest", 
"best" or "better",

76
00:03:24,986 --> 00:03:27,933
it can suggest we are looking 
at an opinion statement.

77
00:03:28,719 --> 00:03:30,973
Another type of opinion is a prediction.

78
00:03:31,564 --> 00:03:35,307
Often predictions are based
on experience, knowledge or research,

79
00:03:35,546 --> 00:03:37,779
but because they are based on the future,

80
00:03:37,889 --> 00:03:39,887
we can't actually verify them today.

81
00:03:40,236 --> 00:03:41,552
Let's look at an example.

82
00:03:41,931 --> 00:03:46,209
Driverless cars will represent
10% of all cars on the road by 2026.

83
00:03:46,948 --> 00:03:48,829
That sounds both amazing and scary.

84
00:03:49,225 --> 00:03:53,055
Although many auto manufacturers are
developing self-driving car technology,

85
00:03:53,055 --> 00:03:55,436
we have no way of verifying
the statement today.

86
00:03:55,725 --> 00:03:57,476
So, it is an opinion.

87
00:03:58,093 --> 00:04:01,589
One thing to remember is that just
because we believe something to be true,

88
00:04:01,589 --> 00:04:03,655
that doesn't make it a fact.

89
00:04:05,088 --> 00:04:06,968
Let's recap what we learnt.

90
00:04:08,189 --> 00:04:11,207
A fact is a statement
that can be proven to be true.

91
00:04:11,672 --> 00:04:13,912
Can it be measured,
or confirmed with data?

92
00:04:14,151 --> 00:04:15,324
Can it be observed?

93
00:04:15,843 --> 00:04:18,226
Can we verify its truth
with other sources?

94
00:04:18,542 --> 00:04:19,782
Does it stay the same?

95
00:04:20,392 --> 00:04:22,856
If we answer "yes"
to one of these questions,

96
00:04:23,072 --> 00:04:24,799
then it means it is a fact.

97
00:04:25,443 --> 00:04:27,729
An opinion is a statement 
of belief or judgement

98
00:04:27,729 --> 00:04:29,478
that cannot be proven true.

99
00:04:29,478 --> 00:04:31,310
Does it evalute someone or something?

100
00:04:31,559 --> 00:04:32,641
Can we debate it?

101
00:04:32,804 --> 00:04:34,120
Does it make a prediction?

102
00:04:34,479 --> 00:04:35,632
Can it change?

103
00:04:36,091 --> 00:04:38,151
If you answer "yes" 
to these questions,

104
00:04:38,151 --> 00:04:39,181
it is an opinion.

105
00:04:40,171 --> 00:04:42,717
Knowing how to separate
between fact and opinion

106
00:04:42,964 --> 00:04:44,614
helps us to understand information

107
00:04:44,614 --> 00:04:46,699
and shape our own beliefs about the world.

108
00:04:46,936 --> 00:04:49,261
Try it and see if you can
use these questions

109
00:04:49,261 --> 00:04:51,221
to tell the difference in your own life.

110
