IB ESS SL 1.1 Perspectives Paper 1 & 2 Core skill ~12 min read

How Values Shape Environmental Views

Values are the layer underneath a perspective. They are quieter and harder to see, which is exactly why ESS bothers to measure them — through value surveys, and through graphs that track what people actually do over years rather than what they say once.

📚 What you need to know

What values are

Values are the principles a person treats as worth something: honesty, fairness, loyalty, compassion, independence. They are not opinions about a particular issue — they are the standards used to judge every issue.

That makes them powerful. Values quietly decide what you notice, what you tolerate, and what you would be prepared to give up.

From values to action values sit underneath everything you decide VALUES what you believe matters most PERSPECTIVE how you see a particular issue CHOICES what you actually do about it and what you do slowly reshapes what you value Surveys are useful because they reach the layer below behaviour.
The dashed arrow is the part people forget. Habits change values as well as the other way round, which is why sustained campaigns work better than one-off appeals.

Where values come from, and where they show

LevelHow values appearExample
The individualThey shape priorities, judgements and everyday choicesChoosing to walk rather than drive because you value low-impact living
CultureWhole societies hold values in common, learned rather than chosenIn many cultures, deference to elders shapes how decisions get made at all
The communityValues are shared and reshaped through how people talk and act togetherA neighbourhood that values its river organises clean-ups and backs green policies
OrganisationsVisible in advertising, social media, published policies and actual decisionsA clothing company donating a share of profits to conservation is signalling stewardship
MovementsValues scale up into collective demands for changeYouth climate strikes turned a shared value into sustained pressure on policymakers
Be a little sceptical about stated organisational values. What a company says in an advertisement and what it does in its supply chain can be very different, and an evaluation question is often really asking you to spot that gap.

When values clash

Different values create tension, between individuals and between organisations. The conflict is rarely about facts. It is about which principle should win when two good things cannot both be had.

In multicultural societies these tensions are constant, and managing them takes understanding of and respect for different values — not a ruling on who is correct. That framing matters in your answers.

Value surveys

A value survey investigates how a social group sees a set of environmental issues, and which of them the group treats as important. It is the standard tool for turning something invisible into data.

🧩 Designing one that works

  1. Decide what you actually want to know — attitudes to renewable energy, to waste, to public transport. A vague survey produces vague data.
  2. Build in different viewpoints. Questions written from one standpoint will only find people who share it.
  3. Aim to capture the whole range of opinion in the group, including the views you did not expect.
  4. Choose your question types deliberately — closed for numbers, open for reasons.
  5. Sample properly. A group is not uniform, and a survey of your friends is a survey of your friends.
  6. Repeat it later if you want to see change rather than a snapshot.
Two kinds of survey question you usually want both, for different reasons CLOSED QUESTIONS fixed options to choose from How likely are you to cycle to school? 1 – 2 – 3 – 4 – 5 easy to count and graph OPEN QUESTIONS answered in their own words What stops you cycling to school? richer, but harder to analyse Closed data tells you what. Open data tells you why.
Multiple-choice items, rating scales and agree-to-disagree scales are all closed. Each answer becomes a number, and numbers can be tested for trends and correlations.
MethodStrengthLimitation
Online survey toolsReach a wider audience, gather more data, do it faster, and analyse it efficientlyOnly reaches people who are online and willing to respond, which biases the sample
Closed-ended questionsProduce structured data that can be quantified and analysed statistically to reveal trends, correlations and patternsRespondents can only pick from options you thought of
Open-ended questionsCapture detail and reasoning you would never have predictedTime-consuming and difficult to analyse consistently
InterviewsAllow follow-up questions and clarificationSlow, and the interviewer can influence the answer

Pairing survey data with real data

Attitudes on their own prove very little. The strong move is to correlate them with a measured behaviour — survey attitudes to recycling, then compare with the actual mass of material recycled. Agreement between the two is a real finding; a gap between them is a more interesting one.

Behaviour-time graphs

Run the same survey again next year, and the year after, and you can plot how a behaviour or lifestyle is changing. That is a behaviour-time graph, and it turns a set of snapshots into a trend.

A behaviour-time graph repeat the same survey each year and the shift becomes visible 0 10 20 30 40 campaign starts here 2019 2020 2021 2022 2023 2024 2025 year students cycling to school / %
The line was already drifting upwards before the campaign. That matters: some of the later rise would have happened anyway, and a good evaluation says so.
What behaviour-time graphs can trackWhat they are used for
Energy consumption in the homeMonitoring progress towards a sustainability target
Waste generated and recycling ratesEvaluating whether an environmental initiative actually worked
Transport choices — driving, cycling, public transportVisualising the impact of a specific intervention
Water use and composting habitsIdentifying where further improvement is possible

Writing survey questions

A student wants to investigate attitudes to single-use plastic in their school. Write one closed and one open question, and justify each choice. (4 marks)

Closed question “On a scale of 1 to 5, how important is reducing single-use plastic to you personally?” justification: every answer becomes a number, so the results can be totalled, averaged and tested for trends across year groups Open question “What would make it easier for you to use less single-use plastic at school?” justification: it captures reasons the student would never have listed as options, such as a lack of water fountains One question for the numbers, one for the reasons behind them the closed question measures the value; the open one explains the gap between the value and the behaviour

Interpreting a behaviour-time graph

Using the graph above, describe the trend and evaluate the claim that the campaign caused the change. (5 marks)

Describe: before the campaign Cycling rose slowly from 12 % in 2019 to 18 % in 2022, an increase of six percentage points over three years. Describe: after the campaign From 2022 the line steepens sharply, reaching 38 % by 2025 — twenty percentage points in three years. Evaluate: the case for the campaign The change in gradient coincides with the campaign, and the size of the increase is much larger than the earlier drift. Evaluate: the case against Cycling was already rising before 2022, so part of the later increase may be continuation of an existing trend. Other factors could also be responsible — new cycle lanes, fuel prices, or a change in school policy. A strong association, but correlation on its own does not prove the campaign caused it “the trend began before the intervention” is the single most useful sentence in graph evaluation questions

Limitations of a value survey

A survey of one class finds 90 % agree that protecting biodiversity is important. Outline two limitations of using this to describe the whole school. (3 marks)

Limitation 1: the sample One class is not representative of the school. Students of a similar age, and possibly studying similar subjects, may share attitudes that other year groups do not. Limitation 2: what agreement measures Agreeing that something is important is cheap. The survey measures a stated value, not behaviour, and the two often diverge. How to improve it Sample randomly across year groups, and pair the attitude question with a measured behaviour. Unrepresentative sample, and stated values are not actions remember that a group is never uniform — even one class contains a range of views
