The Availability Heuristic01:08

The Availability Heuristic

7.1K
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 Representativeness Heuristic

The representative heuristic describes a biased way of thinking, in which you unintentionally stereotype someone or something. For example, you may assume that your professors spend their free time reading books and engaging in intellectual conversation, because the idea of them spending their time playing volleyball or visiting an amusement park does not fit in with your stereotypes of professors.

The Anchoring-and-Adjustment Heuristic

7.8K
In order to make good decisions, we use our knowledge and our reasoning. Often, this knowledge and reasoning is sound and solid. However, sometimes, we are swayed by biases or by others manipulating a situation. For example, let’s say you and three friends wanted to rent a house and had a combined target budget of $1,600. The realtor shows you only very run-down houses for $1,600 and then shows you a very nice house for $2,000. Might you ask each person to pay more in rent to get the...

Heuristics

741
Heuristics are problem-solving strategies that use mental shortcuts to simplify decision-making. Unlike algorithms, which must be followed precisely to achieve a correct result, heuristics offer a general problem-solving framework. They save time and energy but can sometimes lead to less rational decisions.
People often rely on heuristics when faced with an overload of information, limited time, low importance of the decision, limited information, or when a heuristic readily comes to mind. For...

Base complementarity between the three base pairs of mRNA codon and the tRNA anticodon is not a failsafe mechanism. Inaccuracies can range from a single mismatch to no correct base pairing at all. The free energy difference between the correct and nearly correct base pairs can be as small as 3 kcal/ mol. With complementarity being the only proofreading step, the estimated error frequency would be one wrong amino acid in every 100 amino acids incorporated. However, error frequencies observed in...

Area of Science:

  • Clinical informatics
  • Patient safety
  • Healthcare quality improvement

Background:

  • Sepsis is a life-threatening condition requiring prompt recognition and treatment.
  • Electronic sepsis alert systems are used to aid early sepsis detection in hospitals.
  • The effectiveness of these alerts depends on their usability, including interface and information design.

Purpose of the Study:

  • To conduct a usability inspection of a clinician-facing electronic sepsis alert system.
  • To identify specific usability problems within the sepsis alert system.
  • To advocate for the systematic use of usability inspections in healthcare technology.

Main Methods:

  • A usability inspection methodology was applied to evaluate a sepsis alert system.
  • The inspection assessed the system against established usability principles.
  • The number of usability principle violations was quantified.

Main Results:

  • The sepsis alert system exhibited significant usability problems.
  • Violations were identified across 12 out of 14 assessed usability principles.
  • These findings indicate substantial room for improvement in the system's design and user experience.

Conclusions:

  • The usability of electronic sepsis alert systems is crucial for their effectiveness in clinical practice.
  • Systematic usability inspections can effectively identify critical flaws in healthcare technology.
  • Improving the usability of sepsis alert systems is essential for enhancing sepsis recognition and patient outcomes.
