Linescale is a "tough test." Tough to be scored an Acceptor. It’s more than "Intention to buy." That’s just applause. Saying you like it doesn’t mean you’ll switch to it.
Linescale follows real world decision making. An Acceptor prefers your concept to what she is doing today.
(a) the product is on the shelf and visible
(b) messaging communicates the product as tested
(c) sufficient frequency reached the population
(d) price is at the acceptable tested level
(e) competition does not effectively counter your marketing*
*Nielsen Bases factors in estimates of likely marketing variables — a far more elaborate and lengthy process. Linescale assumes you market effectively.
