145 good cause and effect topics
Captivating cause and effect ideas for student speeches and essays
By: Susan Dugdale | Last modified: 11-04-2023
Cause and effect topics explore actions and their consequent reactions. They explain why something happened.
For instance, cause and effect analysis helps us understand questions or topics like:
- Why does the sun set?
- What are the consequences of being popular?
- Why was there another World War (1939 – 1945) after World War One (1914 - 1918), which was supposed to be the ‘War to End All Wars’?
Anything, and everything, can be looked at in terms of cause and effect.
There are 145 themed, good cause and effect topics here - suitable for either a speech or an essay.
In addition, there's explanations of terms, examples and other material to help you prepare the best speech or essay you possibly can.
Challenge yourself! Choose a topic that connects in a real way with your audience and make your assignment count. ☺

What are causes? What are effects?
A cause is the catalyst setting up, triggering, or initiating a response. It always comes first.
The response or result is the effect or consequence of the cause. It always follows.
Here’s a very simple example.
When the door slammed shut on my finger, I yelped in pain.
The cause is the ‘why’ preceding, coming before, the effect, the ‘what’.
‘The door slammed shut on my finger’ is the cause, or the reason why 'I yelped in pain’.
‘I yelped in pain’ is the effect or what happened as a consequence of the cause.
Cause-and-effect cannot exist without each other
Either one cannot exist without the other. There is no effect without a cause or a cause without an effect.
Absolutely everything is part of an ongoing causal chain: cause followed by effect followed by cause followed by effect, followed by...
The causal chain: ongoing cause-and-effect
To illustrate here’s my 'the-door-slammed-on-my-finger' example continued. The effect becomes the cause giving rise to a new effect. And so, it rolls on.
When I yelped in pain, (cause) I gave my colleague such a fright she spilled her coffee. (effect)
When she spilled her coffee (cause) it splashed all over the notes she was getting ready to take to a meeting. (effect)
Because her notes were covered in coffee stains, (cause) she had to print them out again. (effect)
Because she had to print them out again, (cause) she was late for her meeting. (effect)
Cause-and-effect analysis - Fish Bone Diagram
An effect may have one or multiple causes, and one cause may have multiple consequences.
For example, the outbreak of World War Two (the effect) did not have a single cause. Although the actual declaration of war between Britain and Germany was triggered by Germany invading Poland, that was just the immediate cause – the one prior to the event. Many more preceded it.
A fish bone diagram, a visual analytical tool, also known as an Ishikawa diagram after the man who invented it, will help you get a good clear overview of a complex topic like this one.
As you can see, the diagram takes its name from the skeleton of a fish.
Each major ‘bone’ arising from either side of its central ‘back bone’ represents one broad category or cause. Each of these categories or causes can be broken down into smaller ‘bones’ - a sub-set of causes within the major ones.
They all combine to cause the event named in the rectangle representing the head of the fish.
Cause-and-effect analysis World War Two
The diagram clearly shows there were many more reasons aside from Germany invading Poland that led to another world war, only twenty-one years after the end of the first.
The initial cause was the way the defeated countries were dealt with by the victors and how the victors treated one another at the Paris Peace Conference in 1919 where the details of the Treaty of Versailles were worked out.
Italy and Japan, allies of Britain, France and America, were dissatisfied with their outcomes while the conditions of the Treaty that Germany was forced to sign were deliberately humiliating. That simmering discontent eventually emerged as the rise of fascism in Italy, Nazism in Germany and statism (a mix of nationalism, militarism and “state capitalism”) in Japan.
And that's only part the story: the beginning. To give the full picture we have to add the categories or causes, as yet unmentioned: the failure of the League of Nations, the Great Depression, expansionism and the policy of appeasement.

Words and phrases for cause-and-effect topics
Words that communicate the relationship between causes and their effects are called signal or transition words.
They’re signaling (telling) listeners (or readers) to connect the cause(s) with the effect(s). Or to put it another way, to make the transition linking or bridging the cause(s) and the effect(s).
Signal words make it easier for people to understand what is being said. For that reason, you’ll want to use them in the piece you’re preparing.
Here are three examples. The signal words are highlighted.
As a result of his thorough preparation, he easily passed the test.
Because it’s raining, we’ve cancelled the picnic.
Due to Covid, we’ve been working from home.
The benefits of cause-and-effect topics for speeches or
essays
Why do your teachers set cause-and-effect types of essays or speeches? (And the answer is not because they absolutely adore assessing their student's work. ☺)
It's because cause-and-effect assignments will help you:
- develop logical critical thinking skills
- learn to dive deeper into a subject – to go beyond the superficial, to be curious, to ask why rather than be satisfied with an initial, sometimes overly simple, explanation
- learn to systematically analyze the causes of the problem you're looking at, rather than be overwhelmed by it and not know the best way or where to start
- learn to make and test connections to see the different ways things work, or don’t work, together
Crooked cause-and-effect thinking
Because a cause comes before an event, we might be tempted to think a particular cause is the reason the event occurs. It may seem logical. But that is an assumption, one that is not always either trustworthy or the full story!
For example:
We all wore the same blue dresses and therefore we all passed our exams.
Really? Is wearing blue dresses why you all passed?
Did you all revise and study for the examination?
Did you all come refreshed, on time and ready to do your best?
That you all wore blue dresses is immaterial - a false correlation that has no bearing on the outcome. It is co-incidental!
Or:
It was raining when he crashed the car.
Did the rain cause him to crash? Or were there other reasons that could have played a part?
Was he driving too fast?
Was he over tired or over wrought? Maybe he’d worked a double shift or had a major argument.
Was he driving under the influence of either a drug or alcohol?
Was he a licensed driver?
Could he see clearly?
What was the condition of the road? Did he swerve to avoid a large pothole?
Was there stock on the road? Escaped cattle from a farm bordering the road?
Had the car been serviced recently? Were the brakes working as they should?
Both are examples of logical fallacy: a faulty cause and effect connection. A fallacy is a mistaken belief based on unsound arguments and in these instances, the logic was flawed.

22 history examples of cause-and-effect topics
Danish philosopher and theologian Søren Kierkegaard is frequently given the credit for the saying: ‘Life can only be understood backwards; but it must be lived forwards.’
In essence, it’s about the dilemma of only being able to get a clear overview of an event once it is passed yet having to live in the present. Hindsight – the ability to look back and reflect on the past, to see and analyze the patterns of action and reaction, helps us to understand why we are where we are now.
