Confirmation Biases01:31

Confirmation Biases

8.6K
The confirmation bias is the tendency to focus on information that confirms our existing beliefs and ignore information that is inconsistent with our expectations. For example, if you think that your professor is not very nice, you notice all of the instances of rude behavior exhibited by the professor while ignoring the countless pleasant interactions he is involved in on a daily basis. Have you ever fallen prey to the confirmation bias, either as the source or target of such bias?

Regression Toward the Mean01:52

Regression Toward the Mean

7.3K
Regression toward the mean (“RTM”) is a phenomenon in which extremely high or low values—for example, and individual’s blood pressure at a particular moment—appear closer to a group’s average upon remeasuring. Although this statistical peculiarity is the result of random error and chance, it has been problematic across various medical, scientific, financial and psychological applications. In particular, RTM, if not taken into account, can interfere when...

Conservation of Declining Populations

13.6K
Conservation of declining population focuses on ways of detecting, diagnosing, and halting a population decline. The approach uses methods to prevent populations from going extinct.

The Availability Heuristic01:08

The Availability Heuristic

7.3K
A heuristic is a general problem-solving framework (Tversky & Kahneman, 1974). You can think of these as mental shortcuts that are used to solve problems. Different types of heuristics are used in different types of situations, and the impulse to use a heuristic occurs when one of five conditions is met (Pratkanis, 1989):

The Effect of Aging on Tissues01:19

The Effect of Aging on Tissues

4.1K
Several body functions deteriorate with age. The external signs of aging are easily identifiable. For example, the skin becomes dry, less elastic, and thins out, forming wrinkles. The skin of the face begins to appear looser due to a decrease in the levels of elastic and collagen fibers in the connective tissue. Additionally, melanin production in the hair follicle decreases with age, resulting in gray hair. Moreover, the senses of sight and hearing decline, so glasses and hearing aids may...

Decreased pulse rate01:14

Decreased pulse rate

1.0K
Bradycardia is a medical condition in which the heart rate is slower than normal. It occurs when the heart's natural pacemaker, the sinus node, generates slower electrical impulses than the standard rhythm. In adults, bradycardia is diagnosed when the pulse rate falls below 60 beats per minute, indicating a deviation from the normal heart rate range.
There are specific risk factors that can elevate the likelihood of developing bradycardia. Advanced age is a significant factor, with...

Summary
This summary is machine-generated.

Web article popularity declines over time, following a predictable power law. This decay is primarily due to decreased visibility on website front pages, not just novelty.

Area of Science:

  • Digital media analytics
  • Information science
  • Web analytics

Background:

  • Understanding user engagement with online content is crucial.
  • Previous models of content decay have focused on novelty or complex human dynamics.

Purpose of the Study:

  • To analyze the decay patterns of web article access statistics.
  • To identify the primary drivers behind the decline in content attention over time.

Main Methods:

  • Analysis of access statistics for 150 blog entries and news articles.
  • Statistical modeling to identify power law relationships.
  • Comparison of proposed decay explanations against empirical data.

Main Results:

  • Web article access rates follow an inverse power law decay with time, holding up to 1,000 days.
  • Decay exponents vary across different platforms, ranging from 0.6 to 3.2.
  • Visibility reduction on website front pages is the most plausible explanation for attention decay.

Conclusions:

  • The "visibility decay" model effectively explains observed content access patterns.
  • Novelty-based or complex human dynamics theories are insufficient to account for the data.
  • This research provides a quantitative understanding of online content longevity.
