Informal Fallacy: Argument from Repetition


The argument from repetition, also known as argumentum ad nauseam, is a logical fallacy that occurs when a statement is repeated so frequently that it is accepted as true without supporting evidence. Argument from repetition is a rhetorical device used to make a point by repeating the same argument over and over again. This technique is often used to emphasize a particular point, persuade others to agree with a particular viewpoint, or to create a sense of certainty and credibility. 

  • Examples:

  1. In physiology, this fallacy might manifest as the repeated assertion that a specific diet universally leads to better health, despite conflicting studies. 
  2. In medicine, it could be the persistent claim that a particular drug is effective, ignoring evidence of adverse effects or limited efficacy. 
  3. Pharmacy may see this fallacy in the form of repeated endorsements of a supplement's benefits without substantial clinical trials.
  4. In astronomy, one might encounter the repeated proclamation of an impending catastrophic event, like an asteroid impact, without credible scientific backing. 
  5. In dentistry, the fallacy might appear as the continuous promotion of a specific treatment as the best option, without considering individual patient needs or alternative treatments.
  6. In dentistry, a specific dental practice might be deemed necessary due to constant repetition in dental literature, disregarding the need for updated clinical trials. 
  7. In neurology, the oft-repeated myth that humans use only 10% of their brains persists despite neurological evidence to the contrary.
  8. Economics can be influenced by the repeated assertion that a particular policy will lead to economic growth, even if data suggests otherwise. 
  9. Economics can suffer from this fallacy when a particular economic policy is advocated over and over again without proper analysis of its outcomes.
  10. Political discourse is rife with this fallacy, where a slogan or idea is repeated until it is uncritically accepted by the public. 

Conclusion:

Argument from repetition is a powerful rhetorical device that is commonly used to convey a message, persuade others, and establish the validity of a particular idea or theory. Recognizing the argument from repetition fallacy is crucial across all fields to ensure that conclusions are based on evidence and sound reasoning, rather than the persuasive power of repeated assertions.

Points to Ponder:

One always need to be vigilant to persistent media claims.

Deserts: Classifications

Image
Classification of Deserts: Deserts are regions that receive very little rainfall and have a high evaporation rate. They cover about one-fifth of the Earth's land surface and can have different climates, vegetation and wildlife. There are several ways to classify deserts based on their geographical location, dominant weather pattern, temperature and moisture. The most common classification system divides deserts into five types: subtropical, coastal, rain shadow, interior and polar.    Subtropical deserts  are located in the tropics, where hot and dry air masses create high pressure zones that prevent cloud formation and precipitation. Examples of subtropical deserts are the Sahara, the Arabian and the Kalahari.   Coastal deserts  are found along the western coasts of continents, where cold ocean currents create stable and dry air masses that move inland. Examples of coastal deserts are the Atacama, the Namib and the Baja California.   Rain shadow deserts  are formed on the leeward

CELL: FUNCTIONS

Image
The functions of cells Cells perform a variety of functions that are essential for the survival and reproduction of living organisms. Some of the main functions of cells are: -  Metabolism : The  sum of all the chemical reactions  that take place in the cell  to convert or use energy . Metabolism includes  catabolism , which is the  breakdown of molecules to release energy ; and  anabolism , which is the  synthesis of molecules to store or use energy . -  Growth : The  increase in size or number  of cells. Growth can be achieved by  cell enlargement or cell division .  Cell division  is the process by which a  cell splits into two identical daughter cells . There are two types of cell division:  mitosis , which  produces two diploid (2n) cells that are genetically identical to the parent cell ; and  meiosis , which  produces four haploid (n) cells that are genetically different from the parent cell and each other . -  Differentiation : The  process  by which a  cell changes its structu

Earth: Hydrosphere

The hydrosphere is the term used to describe all the water on Earth, in any form. A planet's hydrosphere can be liquid, vapor, or ice . The hydrosphere includes water that is on the surface of the planet , underground , and in the air .  It includes oceans, seas, lakes, rivers, glaciers, ice caps, snow, groundwater, clouds, and water vapor. The hydrosphere covers about 71% of the Earth's surface and contains about 97% of the Earth's water . Some of the factors that affect the hydrosphere are precipitation, evaporation, transpiration, runoff, infiltration, percolation, melting, freezing, erosion, sedimentation, pollution, and climate change. Water Cycle The water cycle, also known as the hydrologic cycle , is the continuous movement of water between the Earth's surface and the atmosphere . The water cycle is essential for life on Earth, as it regulates the climate , distributes freshwater , and shapes the landscape. The water cycle has four main stages: evaporation, con
