Summary
Social proof, availability and mere exposure drive "must-have" feelings; algorithms reinforce filter bubbles and confirmation bias. This article explains the psychology of "grass planting," how algorithms amplify bias, a three-step rational response (needs first, multi-source compare, delay one day), and how to assess KOL/KOC recommendations.
1. The psychology behind "grass planting"
“Everyone uses it–and “influencers recommend it–trigger social proof; algorithms reinforce filter bubbles. Availability heuristic: Availability inflates how "popular" a product feels. Mere exposure: Mere exposure increases liking. Bandwagon: Bandwagon effect creates pressure to buy. Clarify need and budget first; search and compare from multiple sources; delay by a day. See How to avoid impulse buying and How to read and evaluate online reviews?
2. How algorithms amplify bias
Filter bubbles (Pariser 2011) and confirmation bias reinforce "should buy"; browse–buy loop amplifies impulse.
3. Three-step rational response
Needs first; multi-source compare (use evaluate reviews, reading reviews); delay one day. Use selection immunity.
4. Assessing KOL/KOC recommendations
Check interest disclosure, consistency, verifiable info and counter-info (negative reviews) to reduce confirmation bias.
Conclusion
"Grass planting" uses social proof, availability and mere exposure; algorithms amplify bubbles and confirmation bias. Respond with needs first, multi-source compare and delay one day; assess KOL/KOC with disclosure, consistency and counter-info.
