What is the central idea of groupthink as discussed in the passage?

Passage

Read the following passage and answer the questions based on the passage: Group thinking, often referred to as groupthink, is a psychological phenomenon wherein the desire for unanimity within a group overrides the motivation to appraise alternative viewpoints critically. It frequently leads to flawed decision-making because dissent is either internally suppressed or socially penalized. Social conformity, its close ally, describes the act of aligning one's beliefs or behaviours with those of a majority, often subconsciously, in pursuit of acceptance or avoidance of conflict. In tightly knit groups—such as corporate boards, political committees, or academic panels—individual members may refrain from expressing contrarian ideas, fearing ostracization or reputational risk. Over time, this collective homogeneity breeds intellectual stagnation, reducing innovation and enhancing vulnerability to strategic errors. The infamous Bay of Pigs invasion and the Challenger space shuttle disaster are frequently cited as textbook examples of decisions marred by groupthink. Psychologically, the roots of group conformity lie in our evolutionary inclination toward tribal belonging, where deviation was historically associated with survival risk. In modern society, the same instinct manifests through peer pressure, organizational culture, and digital echo chambers. Algorithms reinforce conformity by curating information bubbles that validate existing biases while filtering out divergent thought. However, the remedy to such cognitive myopia lies in institutionalizing dissent. Constructive disagreement, when encouraged within teams or communities, acts as an intellectual safeguard against tunnel vision. Promoting a culture where counterarguments are respected rather than reprimanded can lead to more robust, balanced, and resilient decision-making. In an age dominated by viral trends, polarized discourse, and performative alignment, the courage to question consensus is both rare and essential. True progress emerges not from blind allegiance to majority norms, but from critical inquiry and the audacity to challenge the comfortable.

Question

What is the central idea of groupthink as discussed in the passage?

1. A. Collaborative brainstorming
2. B. Valuing consensus over critique (Correct answer)
3. C. Trusting only experts
4. D. Promoting decentralization

Correct Answer

Option B — Valuing consensus over critique

Detailed Solution & Explanation

The correct answer is Valuing consensus over critique.

Key Points

• The passage defines groupthink as the state in which the desire for unanimity overrides the motivation to appraise alternative viewpoints critically.
• That is precisely "valuing consensus over critique" — agreement is prioritised and dissent is either suppressed internally or penalised socially.
• Option A inverts the idea: collaborative brainstorming invites competing views, which is the safeguard against groupthink rather than its definition.
• Options C and D are never advanced as the phenomenon's core — the passage discusses expertise and structure only in passing.
• For central-idea questions, locate the sentence that defines the term and paraphrase it; the answer restates that definition rather than an example of it.

Additional Information

• Comprehension questions fall into recognisable types — central idea, specific detail, inference, vocabulary in context and tone — and each rewards a different reading strategy.
• For central-idea questions, find the sentence that defines the subject or states the thesis; the answer paraphrases it rather than quoting an example.
• Read the questions before the passage where time allows, so the second reading is targeted at what is actually asked.
