Berger and Milkman

A

2012

Content that evokes high-arousal positive (awe) or negative (anger or anxiety) emotions is more viral. Content that evokes low-arousal, or deactivating, emotions (e.g., sadness) is less viral. To go viral, marketers need to evoke high-arousal emotions.

Q

Boyd and Crawford definition of big data

A

2012

We define Big Data as a cultural, technological, and scholarly phenomenon that rests on the interplay of:

(1) Technology: maximizing computation power and algorithmic accuracy to gather, analyze, link, and compare large data sets.
(2) Analysis: drawing on large data sets to identify patterns in order to make economic, social, technical, and legal claims.
(3) Mythology: the widespread belief that large data sets offer a higher form of intelligence and knowledge that can generate insights that were previously impossible, with the aura of truth, objectivity, and accuracy.

Q

Keiningham et al.

A

2003

Net Promoter, like any measure of customer intentions, is inherently unreliable. Customer intentions may point in the right direction for some behaviors, but they will never provide all of the information needed to understand the complete picture.

Second, managers must be willing to do whatever level of analysis is required to understand their customers and their particular market opportunities.

Q

Reichheld

A

2003

Introduces the NPS score, a 1-10 score for “How likely is it that you would recommend [company] to your friend?”|

In an industry, highest NPS have 2.5x growth rates.

Claims that everything needed to predict growth can be explained with NPS, and asserts that other survey-based mertics such as customer satisfaction have no link to growth

Q

Keiningham et al.

A

2009

Contrary to Reichheld, says that NPS is not a good predictor of growth, and is inferior to customer satisfaction and previous spending.

Any measure of customer intentions (like NPS) is inherently unreliable.

Managers need to understand the entire picture, and do whatever level of analysis needed to do so.
