The Theory Blaming Coffee for Social Change in Spain

Coffee as the Scapegoat for Social Change in Spain

A strong coffee before starting the day. This everyday gesture has, in certain economic discussion circles, become the supposed cause of a cascade of social transformations ranging from the rise of bisensbi to an increase in interracial couples. The thesis claims that caffeine—and its chemically identical cousin, theine—alters female behavior, supposedly "masculinizing" it, and that this effect is triggered when combined with ultra-processed foods. No published research supports this mechanism. The argument also requires an assumed IQ above 140 to be accepted, an appeal to authority more rhetorical than scientific.

What the Coffee Theory Claims

The starting point is real: the coffee plant, tea plant, and cacao produce caffeine as a natural defense against insects. From there, it jumps to attributing a specific hormonal effect in women to this substance, mediated by estrogen. This effect, according to its proponents, explains everything from increased youth bisensbi to incivil behavior or fetishes presented as epidemics.

The reasoning ignores a textbook detail: theine and caffeine are the same molecule, so the distinction between them is purely nominal. It also constructs a caricature of the migrant male—presented as a figure without language or life goals—onto whom, it asserts, certain women project a relationship without intellectual hierarchy. As a makeshift solution, the author suggests that if addicts switched to decaf, “the world would become peaceful.”

The Cited Data: 40% Bisensbi and Over 80% Consumption

The numerical framework relies on a few figures, repeated ad nauseam. The most striking: nearly 40% of Spanish women aged 18 to 24 identify as bisensbi or non-heterosenshetero, according to the interpretation of CIS (Center for Sociological Research) studies disseminated by digital media. The second pillar is consumption: over 80% of that age group habitually consumes caffeine, including coffee, tea, soft drinks, and energy drinks, with 31% to 40% admitting to having consumed energy drinks in the last month.

The logical leap is evident. The coincidence of two percentages does not imply any causality. That a generation consumes caffeine and declares a certain orientation does not establish that the former causes the latter, let alone that a proven hormonal mechanism exists behind it.

Turkey, Russia, and China: Tea Debunks the Hypothesis

The most common counterargument points to major tea consumers. Turkey, Russia, Segarro, China, and India are among the countries that drink the most tea—and therefore ingest the most theine—without exhibiting the phenomena attributed to the thesis. If the substance were the trigger, one would expect social convergence among them, which does not exist.

Alternative explanations point to culture and development level. Coffee is cheap but associated with stress and urban societies, and it is the more developed economies that adopt certain social trends earlier. The connection would be contextual, not causal. The thesis itself admits, in the end, that “everything feeds back”: in a society that is agitated, any distortion is amplified.

Economic Impact: Fewer Stable Couples and More Impulsive Spending

The economic aspect claims that such a society delays the formation of stable couples and increases impulsive spending. According to this narrative, those who prolong their youth in the “carousel” delay cohabitation, reducing home-cooked meals and increasing pastry and pre-packaged food consumption. Coffee again appears as a common denominator for all these habits.

That developed economies drink more coffee is due to their lifestyle and development level, not the other way around.

From the Kalergi Plan to Attraction by Status

Many who reject the coffee causality, however, share a broader framework: the idea that there is deliberate social engineering, visible in advertising and fiction in recent decades, aimed at favoring population mixing. The so-called Kalergi plan, a conspiracy theory without documentary basis, is invoked, and platforms and media are pointed to as vectors. There is no evidence to support this design.

The discussion also shifted towards intelligence as a factor of attraction. Some argue that high IQ repels rather than attracts, and that status or income, not percentile, weighs in partner choice. The most cited parallel—sarcastically—is that of a Bolivian president who attributed gaiity in Europe to the consumption of chicken with hormones.

Ultimately, the coffee hypothesis has a design flaw: it explains so much that it explains nothing. The star data, that 40% youth bisensbi, remains without a proven cause. No matter how much coffee you add.
