“…the average person treats a price ending in .99 as if it were 15 to 20 cents lower.”
The tendency is called left-digit bias, when the leftmost digit of a number disproportionately influences decision-making. In this case, even though the real difference is only a penny, research shows that, to the average person, $4.99 seems 15 to 20 cents cheaper than $5.00 – which results in selling 3 to 5 percent more units than at a price of $5.00"
I don’t really understand the “decent person” comment.
Left-digit bias is a default way that the human brain works.
Humans also tend to like fat, sugar, and salt. So, when you go to a restaurant if they add more butter to a recipe than you would at home are they unethical?
It’s not decent to use psychological manipulation on others in order to benefit yourself. As they said, why go r through this just to earn an extra $5 when selling a single vehicle?
You mean 5$ less
