1.2 Evidence-based Decision making Flashcards
The goal of evidence based management is
Goal: to improve managers’ (staffing) decision quality.
Evidence based management means
translating principles based on best evidence into organizational practices.
Big ‘E’ evidence
generalizable knowledge regarding cause-effect connections derived from scientific methods (ex. Specific goal setting works).
Little ‘e’ evidence
data systematically gathered in particular setting to inform local decisions (ex. Rigorous situational assessment/job analysis).
Why do managers resist evidence-based management?
Undermines formal authority.
Constrains ability to make decisions (unwanted info)
Speed of decision over accuracy (extra work)
Diminishes previous experience value.
Lack of understanding.
Uncertainty regarding info quality.
Evidence-based managers are:
E-MACS
o Empirical: Rely on data to inform decisions
o Multidisciplinary: Incorporate/aggregate info from different sources
o Adaptable: Update decision when better info available
o Cautious: Express predictions in probabilistic terms/consider options
o Self-critical: Acknowledge limitations of own abilities/avoid overconfidence
What are the Prominent Bias in Staffing
(PCO AW)
Primacy/Recency Effect; Confirmation bias; Overconfidence/optimism; Attractiveness; Weight bias
Primacy/Recency Effect:
when integrating observations, first and last observations will have greater effect on overall rating. (cognitively easier)
What factors affect primacy/recency bias?
Factors: extraversion, appearance, verbal/nonverbal cues, applied social skill, ingratiation
What is confirmation bias?
seeking or interpreting evidence in ways partial to existing beliefs, expectations. Search for supportive info.
T/F: Older workers are less motivated and receptive to change.
False
What are some forms of confirmation bias
- Considering only one single possible explanation
- Overweighting positive confirmatory instances
- Preferential treatment of evidence supporting belief
- Only looking for positive cases
Pre-decision Information Distortion
Prior to deciding, an individual begins to favor a choice option and this tentative preference shifts subsequent info.
Internship (Swider study) example
First 2 weeks of recruitment biggest impact (Swider study). Attraction differed within 2 weeks for organizations accepted offer vs. rejected.
What is overconfidence and what does it lead to
tendency to be too confident in own abilities
* Drive to risky decisions
* Credit self for success; less for failure. Discount role of luck.
