Certain variants of key behavioural genes, “risk allele” make people more vulnerable to certain mood, psychiatric, or personality disorders. An allele is any of the variants of a gene that takes more than one form. A risk allele, then, is simply a gene variant that increases your likelihood of developing a problem.
Researchers have identified a dozen-odd gene variants that can increase a person’s susceptibility to depression, anxiety and antisocial, sociopathic, or violent behaviours, and other problems — if, and only if, the person carrying the variant suffers a traumatic or stressful childhood or faces particularly trying experiences later in life. This hypothesis, often called the “stress diathesis” or “genetic vulnerability” model, has come to saturate psychiatry and behavioural science.
Recently, however, an alternate hypothesis has emerged from this one and is turning it inside out. This new model suggests that it’s a mistake to understand these “risk” genes only as liabilities. According to this new thinking, these “bad genes” can create dysfunctions in unfavourable contexts — but they can also enhance function in favourable contexts. The genetic sensitivities to negative experience that the vulnerability hypothesis has identified, it follows, are just the downside of a bigger phenomenon: a heightened genetic sensitivity to all experience.
This hypothesis has been anticipated by Swedish folk wisdom which has long spoken of “dandelion” children. These dandelion children — equivalent to our “normal” or “healthy” children, with “resilient” genes — do pretty well almost anywhere, whether raised in the equivalent of a sidewalk crack or well-tended garden. There are also “orchid” children, who will wilt if ignored or maltreated but bloom spectacularly with greenhouse care. According to this orchid hypothesis, risk becomes possibility; vulnerability becomes plasticity and responsiveness. Gene variants generally considered misfortunes can instead now be understood as highly leveraged evolutionary bets, with both high risks and high potential rewards.
In this view, having both dandelion and orchid kids greatly raises a family’s (and a species’) chance of succeeding, over time and in any given environment. The behavioural diversity provided by these two different types of temperament also supplies precisely what a smart, strong species needs if it is to spread across and dominate a changing world. The many dandelions in a population provide an underlying stability. The less-numerous orchids, meanwhile, may falter in some environments but can excel in those that suit them. And even when they lead troubled early lives, some of the resulting heightened responses to adversity that can be problematic in everyday life — increased novelty-seeking, restlessness of attention, elevated risk-taking, or aggression — can prove advantageous in certain challenging situations: wars, social strife of many kinds, and migrations to new environments. Together, the steady dandelions and the mercurial orchids offer an adaptive flexibility that neither can provide alone. Together, they open a path to otherwise unreachable individual and collective achievements.
The passage suggests ‘orchids’:
Show Hint
- are insufficient in number.
- are limited to greenhouses.
- end up weaker as compared to dandelions.
- thrive in anaesthetised conditions.
- are always too delicate to survive.
The Correct Option is D
Solution and Explanation
They do not flourish in harsh or natural competitive environments like dandelions do, but in protected, nurtured conditions they thrive and can even surpass others.
- Option A: Insufficient in number – not suggested.
- Option B: Limited to greenhouses – too restrictive, not supported.
- Option C: Weaker than dandelions – misleading; orchids are not inherently weaker, they just need specific conditions.
- Option D: Correct, as they thrive only when carefully supported.
- Option E: Too extreme; they are not "always too delicate to survive."
\[ \boxed{\text{Orchids thrive in anaesthetised conditions.}} \]
Which of the following statements correctly echoes the author’s view?
Show Hint
- Persons carrying risk allele end up being self-destructive and antisocial.
- Orchids possess humankind’s phenomenal adaptability and evolutionary success.
- With a bad environment and poor parenting, all children will have a normal life.
- Children born with genetic vulnerability need not necessarily be sociopaths.
- Genes not only make you sensitive to disorders, but are also responsible for failures of societies.
The Correct Option is D
Solution and Explanation
The passage suggests that genetic vulnerability (such as carrying risk alleles) does not always doom individuals. Environmental influences, upbringing, and resilience play crucial roles in outcomes.
Step 2: Evaluate options.
(A) Incorrect — too absolute, implies all risk allele carriers are destructive. ✗
(B) Incorrect — irrelevant; orchids are unrelated metaphor here. ✗
(C) Incorrect — contradicts logic; bad environment + poor parenting cannot ensure a normal life. ✗
(D) Correct — aligns with the view: vulnerability does not guarantee antisocial outcomes. ✓
(E) Incorrect — overgeneralizes by blaming genes for societal failures. ✗
Step 3: Conclusion.
The author emphasizes that genetic predispositions do not determine destiny; hence, the correct answer is: \[ \boxed{\text{Children born with genetic vulnerability need not necessarily be sociopaths.}} \]
The word ‘diathesis’ means:
Show Hint
- susceptible disease
- two – prolonged hypothesis
- connected with two kidneys
- missing part of the body
- living in two different environments
The Correct Option is A
Solution and Explanation
It does not mean a hypothesis (so option B is wrong).
It is not related to kidneys (option C is wrong).
It does not refer to missing a body part (option D is wrong).
Nor does it describe living in two environments (option E is wrong). Thus, the best definition is: \[ \boxed{\text{susceptible disease / predisposition to disease}} \]
Mr.\ Good and Mr.\ Evil were batch-mates during college. Five years after graduating, Mr.\ Evil was put behind bars for financial fraud while Mr.\ Good was running a successful NGO, working for orphans. Mr.\ Good was raised in a protective environment while Mr.\ Evil was a self-made man. Based on the above information, which of the following statements is definitely correct?
Show Hint
- It can be concluded that Mr.\ Evil is a ‘dandelion,’ but nothing can be concluded about Mr.\ Good.
- It can be concluded that Mr.\ Evil is an ‘orchid’, but nothing can be concluded about Mr.\ Good.
- It can be concluded that Mr.\ Good is a ‘dandelion’, but nothing can be concluded about Mr.\ Evil.
- It can be concluded that both Mr.\ Good and Mr.\ Evil are ‘orchid’.
- It is not possible to conclude about ‘children typology’ of the two batch mates.
The Correct Option is
Solution and Explanation
In the “orchid–dandelion” metaphor, {orchids} are highly sensitive to environment (can flourish or flounder depending on conditions) while {dandelions} are relatively resilient across contexts. The prompt gives no explicit behavioral test or longitudinal evidence to classify either person.
Step 2: Why none of the specific classifications follow.
The facts given—(i) different upbringings ({protective} vs.\ {self-made}) and (ii) divergent outcomes (NGO success vs.\ fraud and jail)—do not logically imply inherent sensitivity or resilience types. Outcomes can be driven by myriad factors (values, opportunities, peer influence, chance events), not solely orchid/dandelion traits.
Step 3: Eliminate options.
(A), (B), (C), (D) assert definite typologies for at least one person, which are {unsupported}. Only (E) correctly states that no definite typology conclusion can be drawn from the information provided.
\[ \boxed{\text{No definitive typology conclusion is possible} \;\Rightarrow\; \text{Option (E).}} \]

- Acrucial moderating factor in how people experience comparisons is self-esteem. Individuals with high self-esteem are more likely to interpret upward comparison as informative rather than threatening. They are more resilient in the face of others’ success and more likely to believe they can reach their own goals. In contrast, people with low self-esteem are more prone to interpret comparison as judgment, reinforcing negative self-views and triggering feelings of inadequacy.
This dynamic creates a self-reinforcing loop. People with high self-esteem are less vulnerable to upward comparison, which intensifies those doubts. Those with a secure sense of self are more likely to use comparison as a learning tool. The same external stimulus—a colleague’s achievements, a friend’s popularity—can have radically different effects depending on internal stability.
Self-esteem also influences how people choose their comparison targets. Research has found that individuals often engage in “selective comparison,” seeking out those who confirm their existing beliefs about themselves. This can become a subtle form of self-sabotage. Someone who feels unworthy may subconsciously seek out targets that reinforce that sense, perpetuating a narrative of inferiority. One of the most promising antidotes to social comparison is temporal comparison—evaluating oneself not against others, but against one’s own past. This method has been shown to increase motivation and satisfaction, especially when individuals can see concrete progress. Temporal comparison activates the same reward circuits as social comparison but avoids the threat systems associated with social ranking. It also reinforces agency: individuals focus on what they can control and improve rather than what others control. In therapeutic and coaching settings, temporal comparison is used to help clients build self-efficacy and track growth over time.
Moreover, people who focus on self-improvement rather than social dominance are less likely to fall into cycles of envy or self-pity. They can still use others as inspiration, but they do so without attaching their self-worth to the outcome. This is not to say they never compare—but that they focus on learning, rather than judgment. The most skilful approach to comparison may lie in eliminating it, but in reframing it as feedback. When we interpret comparison as information rather than a verdict, we can ask, “What can I learn from this?” This shift turns comparison into a growth tool. Teachers mentor their students, not as rivals. Psychologists emphasize that the key variable here is mindset.
A fixed mindset sees comparison as a threat. If someone else is better, it means we are worse. A growth mindset sees comparison as a map. If someone else has reached a certain level, it means the path exists. This reframing is not just a cognitive trick. It changes the emotional tone of comparison, making it more likely to inspire than to wound. Reframing also requires emotional regulation—the ability to notice an initial pang of envy or shame without reacting impulsively. With practice, individuals can learn to pause, reflect, and reinterpret their emotional responses. Over time, this builds resilience and self-trust, allowing comparison to become a learning tool rather than a cage.- XAT - 2026

When people who are talking don’t share the same culture, knowledge, values, and assumptions, mutual understanding can be especially difficult. Such understanding is possible through the negotiation of meaning. To negotiate meaning with someone, you have to become aware of and respect both the differences in your backgrounds and when these differences are important. You need enough diversity of cultural and personal experience to be aware that divergent world views exist and what they might be like. You also need the flexibility in world view, and a generous tolerance for mistakes, as well as a talent for finding the right metaphor to communicate the relevant parts of unshared experiences or to highlight the shared experiences while demphasizing the others. Metaphorical imagination is a crucial skill in creating rapport and in communicating the nature of unshared experience. This skill consists, in large measure, of the ability to bend your world view and adjust the way you categorize your experiences. Problems of mutual understanding are not exotic; they arise in all extended conversations where understanding is important.
When it really counts, meaning is almost never communicated according to the CONDUIT metaphor, that is, where one person transmits a fixed, clear proposition to another by means of expressions in a common language, where both parties have all the relevant common knowledge, assumptions, values, etc. When the chips are down, meaning is negotiated: you slowly figure out what you have in common, what it is safe to talk about, how you can communicate unshared experience or create a shared vision. With enough flexibility in bending your world view and with luck and charity, you may achieve some mutual understanding.
Communication theories based on the CONDUIT metaphor turn from the pathetic to the evil when they are applied indiscriminately on a large scale, say, in government surveillance or computerized files. There, what is most crucial for real understanding is almost never included, and it is assumed that the words in the file have meaning in themselves—disembodied, objective, understandable meaning. When a society lives by the CONDUITmetaphor on a large scale, misunderstanding, persecution, and much worse are the likely products.- XAT - 2026

Later, I realized that reviewing the history of nuclear physics served another purpose as well: It gave the lie to the naive belief that the physicists could have come together when nuclear fission was discovered (in Nazi Germany!) and agreed to keep the discovery a secret, thereby sparing humanity such a burden. No. Given the development of nuclear physics up to 1938, development that physicists throughout the world pursued in all innocence of any intention of finding the engine of a new weapon of mass destruction—only one of them, the remarkable Hungarian physicist Leo Szilard, took that possibility seriously—the discovery of nuclear fission was inevitable. To stop it, you would have had to stop physics. If German scientists hadn’t made the discovery when they did, French, American, Russian, Italian, or Danish scientists would have done so, almost certainly within days or weeks. They were all working at the same cutting edge, trying to understand the strange results of a simple experiment bombarding uranium with neutrons. Here was no Faustian bargain, as movie directors and other naifs still find it intellectually challenging to imagine. Here was no evil machinery that the noble scientists might hide from the problems and the generals. To the contrary, there was a high insight into how the world works, an energetic reaction, older than the earth, that science had finally devised the instruments and arrangements to coart forth. “Make it seem inevitable,” Louis Pasteur used to advise his students when they prepared to write up their discoveries. But it was. To wish that it might have been ignored or suppressed is barbarous. “Knowledge,” Niels Bohr once noted, “is itself the basis for civilization.” You cannot have the one without the other; the one depends upon the other. Nor can you have only benevolent knowledge; the scientific method doesn’t filter for benevolence. Knowledge has consequences, not always intended, not always comfortable, but always welcome. The earth revolves around the sun, not the sun around the earth. “It is a profound and necessary truth,” Robert Oppenheimer would say, “that the deep things in science are not found because they are useful; they are found because it was possible to find them.”
...Bohr proposed once that the goal of science is not universal truth. Rather, he argued, the modest but relentless goal of science is “the gradual removal of prejudices.” The discovery that the earth revolves around the sun has gradually removed the prejudice that the earth is the center of the universe. The discovery of microbes is gradually removing the prejudice that disease is a punishment from God. The discovery of evolution is gradually removing the prejudice that Homo sapiens is a separate and special creation.- XAT - 2026

Brijbhushan, a microfinancier, lends money at the rate of Rs.10 per square meter to small farmers at a village. He charges an annual interest rate of 10%. All the farming plots in that village are rectangular, with areas varying between a minimum of 1000 square meters and a maximum of 10,000 square meters.
This year, Brijbhushan has lent money only to five farmers: Aditya, Binod, Chhuttan, Dabloo and Govind. The perimeter of Chhuttan’s plot is 250 meters, with the length and width being at a ratio of 4:1. Aditya’s plot has an area three times the area of Govind’s plot. The area of Aditya’s plot is also the average of the areas of Govind’s plot and Dabloo’s plot. The plots belonging to Aditya, Binod and Dabloo are of the same width, but of different lengths. Moreover, the length of Binod’s plot is the sum of the lengths of Aditya’s plot and Dabloo’s plot.- XAT - 2026

An investment company, Win Lose, recruit's employees to trade in the share market. For newcomers, they have a one-year probation period. During this period, the employees are given Rs. 1 lakh per month to invest the way they see fit. They are evaluated at the end of every month, using the following criteria:
1. If the total loss in any span of three consecutive months exceeds Rs. 20,000, their services are terminated at the end of that 3-month period,
2. If the total loss in any span of six consecutive months exceeds Rs. 10,000, their services are terminated at the end of that 6-month period.
Further, at the end of the 12-month probation period, if there are losses on their overall investment, their services are terminated.
Ratan, Shri, Tamal and Upanshu started working for Win Lose in January. Ratan was terminated after 4 months, Shri was terminated after 7 months, Tamal was terminated after 10 months, while Upanshu was not terminated even after 12 months. The table below, partially, lists their monthly profits (in Rs. ‘000’) over the 12-month period, where x, y and z are masked information.
Note:
• A negative profit value indicates a loss.
• The value in any cell is an integer.
Illustration: As Upanshu is continuing after March, that means his total profit during January-March (2z +2z +0) ≥
Rs.20,000. Similarly, as he is continuing after June, his total profit during January − June ≥
Rs.10,000, as well as his total profit during April-June ≥ Rs.10,000.
