Confirmation Biases01:31

Confirmation Biases

8.5K
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?

False Memories01:18

False Memories

571
False memories represent a cognitive distortion in which individuals recall events that did not happen, or remember them in an altered form. This phenomenon highlights the brain's constructive nature in processing and recalling memories, emphasizing that memory is not a perfect representation of past events but rather a dynamic reconstruction influenced by various factors.
One primary source of false memories is misattribution, where individuals incorrectly associate external information...

Hindsight Biases

4.5K
Hindsight bias leads you to believe that the event you just experienced was predictable, even though it really wasn’t. In other words, you knew all along that things would turn out the way they did. Can you relate this to the phrase "Hindsight is 20/20" now?

Understanding Deception01:14

Understanding Deception

206
Deception is a pervasive aspect of human communication. Empirical studies have shown that most individuals engage in some form of deceit on a daily basis, with approximately 20% of social exchanges involving deceptive elements. Lying follows a developmental trajectory, peaking during adolescence and declining with age, possibly due to the maturation of cognitive control and social accountability.Cognitive and Social Factors in Deception DetectionDespite its prevalence, accurately detecting...

The Availability Heuristic01:08

The Availability Heuristic

7.2K
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):

Framing Effects03:26

Framing Effects

8.0K
Information is everywhere and its presentation—such as how and when items are presented—can impact our perceptions and decisions surrounding the info. This broad concept umbrellas framing effects—influences that occur due to the way information is framed in its appearance, whether it’s purely the order or the specific wording of a message. Let’s take a look at numerous ways in which two versions of something can objectively say the same thing, yet we respond in...

Summary

The British Red Cross declared a humanitarian crisis due to rising A&E attendances. This highlights critical pressures on emergency healthcare services.

Area of Science:

  • Public Health
  • Emergency Medicine

Background:

  • Rising attendances at Accident & Emergency (A&E) departments are straining healthcare resources.
  • The British Red Cross has formally recognized the severity of the situation.

Purpose of the Study:

  • To analyze the contributing factors to increased A&E attendances.
  • To understand the implications of the declared humanitarian crisis on healthcare access and patient outcomes.

Main Methods:

  • Review of A&E attendance data.
  • Analysis of healthcare system capacity and patient flow.
  • Qualitative assessment of the humanitarian situation.

Main Results:

  • Significant increase in patient volumes exceeding A&E capacity.
