Reading Assumptions, Bias and Framing | 阅读隐含前提、偏向与框架
Critical reading asks how a conclusion is built, not whether we like it.
At C1 direction, readers look beyond explicit claims to the assumptions, categories, comparisons, omissions and framing choices that shape interpretation. This does not mean assuming manipulation. It means examining how the argument works.
批判阅读不是“怀疑一切”，也不是“找作者错”。它是检查：结论依赖什么前提？选择了什么比较？省略了什么？同样事实还能怎样框架？

The critical-reading map | 批判阅读地图
- assumptions
- definitions
- framing
- selection
- comparison groups
- base rates
- loaded language
- omission
- source incentives
- alternative framing
1. Explicit claim | 明示主张
Flexible work is more effective.
This is the claim we can see directly.
2. Hidden assumption | 隐含前提
Possible assumption:
“Effective” is being measured in a way that matters for the decision.
3. Ask what must be true | 问“这个论证要成立，需要什么是真的？”
That question often reveals assumptions.
4. Definition assumption | 定义前提
Words such as:
- success
- effective
- fair
- efficient
- advanced
need criteria.
5. Different definitions create different conclusions | 定义不同，结论会不同
Effective = cheaper may produce one answer.
Effective = better learning outcomes may produce another.
6. Category boundaries | 类别边界
Ask how categories were created:
- beginner vs advanced
- successful vs unsuccessful
- urban vs rural
7. Categories can hide variation | 类别可能隐藏差异
Two people in the same category may still be very different.
8. Framing | 框架
Framing is the way an issue is presented so some aspects become more visible than others.
9. Same facts, different frame | 同样事实，不同框架
90% success rate.
vs
10% failure rate.
Mathematically equivalent, rhetorically different.
10. Gain frame vs loss frame | 收益 vs 损失
- save 20 minutes
- avoid losing 20 minutes
11. Choice of baseline | 基准选择
Performance increased by 50%.
From what starting point? If 2 becomes 3, the percentage sounds large while the absolute change is small.
12. Absolute vs relative change | 绝对变化 vs 相对变化
Both can be accurate. Strong readers ask which one is more informative for the decision.
13. Comparison group | 比较组
A result is hard to interpret without knowing what it was compared against.
14. Missing control | 缺少对照
If everyone improves, is the new method the cause—or would they have improved anyway?
15. Before/after framing | 前后对比
A before/after change may reflect other events that happened at the same time.
16. Selection bias | 选择偏向
Who entered the sample?
- volunteers
- top performers
- people who completed the programme
Selection affects what can be generalised.
17. Survivorship | 幸存者偏向
If we only examine people who completed a difficult course, we may miss those who left.
18. Non-response | 未回应者
People who answer a survey may differ from those who do not.
19. Base rates | 基础概率
A dramatic case matters differently if it is one event among ten or one among ten million.
20. Frequency without denominator | 没有分母
100 complaints means little without knowing how many users or transactions existed.
21. Loaded language | 带立场色彩的词
- reform vs cut
- investment vs spending
- flexible vs unstable
Different words can frame the same event differently.
22. Connotation audit | 隐含色彩审计
Ask whether the vocabulary carries approval, disapproval or emotional pressure beyond the factual claim.
23. Euphemism | 委婉化
A softer term can reduce perceived severity.
24. Dysphemism | 贬义强化
A harsher label can increase perceived severity.
25. Passive voice and agency | 被动与责任
Mistakes were made.
Who made them? The missing agent may matter.
26. Nominalisation and agency | 名词化与责任
The cancellation of the service…
Who cancelled it?
27. Omission | 省略
Every text selects information. The critical question is whether omitted information could materially change interpretation.
28. What is missing? | 缺了什么？
- comparison group
- long-term outcome
- cost
- alternative explanation
- affected subgroup
29. Missing evidence ≠ false claim | 缺证据不等于结论必假
It means confidence should remain limited.
30. Source incentives | 来源激励
Ask whether the source has reasons to emphasise certain outcomes.
31. Incentive does not automatically invalidate | 有利益关系不等于一定错误
Method and evidence still need evaluation.
32. Expertise | 专业性
Does the source have relevant expertise for this specific claim?
33. Scope of expertise | 专业范围
An expert in one field is not automatically authoritative in another.
34. Framing by headline | 标题框架
Headlines compress information and may emphasise the most dramatic angle.
35. Read beyond headline | 不只看标题
Check the article’s actual evidence and qualifications.
36. Framing by graph scale | 图表坐标框架
A truncated vertical axis can make small differences look visually large.
37. Framing by time window | 时间窗口框架
Starting a graph at one date rather than another can change the story.
38. Correlation framing | 相关框架
X linked to Y can sound causal even when the underlying evidence is correlational.
39. Causal language audit | 因果词审计
- caused
- led to
- resulted in
- associated with
- coincided with
These signal different strength.
40. Assumption of one cause | 单一原因假设
Complex outcomes often have multiple causes.
41. Binary framing | 二分框架
online or face-to-face may hide hybrid options.
42. False dilemma | 假两难
Ask whether more than two options exist.
43. Question framing | 问题本身也有框架
Why is X failing? assumes X is failing. A better neutral question may be: How is X performing, and under what conditions?
44. Presupposition | 预设
Some questions or sentences contain assumptions that are treated as already true.
45. Alternative frame | 替代框架
Try rewriting the issue from another legitimate perspective.
46. Example | 例子
Frame A: Remote work reduces office control.
Frame B: Remote work increases employee autonomy.
Both may describe part of the same change.
47. Strong critical reading | 强批判阅读
A strong reader can explain what each frame reveals and hides.
48. Avoid motive guessing | 不要猜动机
Analyse the text’s effects before claiming what the writer intended.
49. Avoid cynical default | 不要默认“都有偏见所以都不可信”
Critical reading distinguishes stronger and weaker evidence rather than rejecting everything.
50. Bias can be systematic without deliberate intent | 偏向可以无意形成
Sampling, measurement and wording can create bias without malicious intent.
51. Mandarin transfer: “立场”与“事实”要分开 | stance vs fact
Track whether a phrase reports evidence, interpretation, evaluation or emotion.
52. Reading practice A | 阅读 A
After the new programme began, completion rose from 40% to 60%. Supporters described the 50% relative increase as a major success. Critics noted that four in ten participants still did not complete the course.
Identify the different frames and explain what each foregrounds.
53. Reading practice B | 阅读 B
A survey of successful programme graduates found high satisfaction. The report concluded that the programme was well received.
What selection issue should a careful reader notice?
54. Reading practice C | 阅读 C
Productivity increased after flexible scheduling was introduced. During the same period, the company also reduced meetings and adopted new software.
Why is a single-cause conclusion unsafe?
55. Reframe practice | 换框架练习
Take one neutral event and write:
- a benefit-focused frame
- a cost-focused frame
- a neutral descriptive frame
56. Assumption audit | 前提审计
For each claim, ask:
- What definitions are assumed?
- What comparison is implied?
- What information is missing?
- What alternative explanation exists?
57. Error clinic | 常见问题
| Problem | Repair |
|---|---|
| I call every perspective “bias”. | Specify the mechanism. |
| I infer bad intent. | Analyse wording/evidence first. |
| I ignore denominator/base rate. | Restore scale. |
| I accept the headline frame. | Read underlying evidence. |
| I find omission and declare claim false. | Lower confidence instead. |
58. First weak link diagnosis | 第一个卡点诊断
- I see claims but not assumptions → premise analysis.
- I see wording but not framing → comparison practice.
- I distrust everything → evidence-weighting problem.
- I miss selection effects → sample reasoning.
- I confuse framing with falsehood → proposition/frame distinction.
59. Seven-day training cycle | 七天训练
| Day 1 | assumptions | 隐含前提 |
| Day 2 | definitions/categories | 定义类别 |
| Day 3 | framing | 框架 |
| Day 4 | selection/base rates | 选择基础率 |
| Day 5 | loaded wording | 词语色彩 |
| Day 6 | alternative frames | 替代框架 |
| Day 7 | three-source framing audit | 综合 |
60. Self-test | 自测
Identify assumptions, definitions, comparison groups, selection effects, base rates, loaded wording and omissions; construct alternative frames without changing facts; distinguish bias mechanisms from accusations of intent.
61. For parents and teachers | 给家长和老师
Require learners to name the specific framing or sampling mechanism rather than using “biased” as a vague criticism.
Reward calibrated uncertainty when evidence is incomplete.
For Mandarin speakers, make the distinction between factual proposition, evaluative wording and rhetorical framing explicit.
