How can you calm your nerves when pitching your startup?
1. Try to enjoy the process and reconnect with how your younger self would have been thrilled to even have the opportunity to play this game (let alone win it). Connect with how exciting it is that you have an idea worth pitching & that investors consider worth listening to. 2. Recall that almost all investors bring the same thing to the table ($$$ ... very few can add any value beyond this). You have something more differentiated than that. Don't place the investor on a pedestal. 3. The stakes are not as big as they seem. In 50 years, no one will remember you or the startup or the investor. It's like a video game with an illusion of reality. 4. Don't fight the nerves. Just feel the anxiety. It too will pass like the passing clouds.

Do I Follow My Friends or the Crowd? Information Cascades in Online Movie Ratings
Management Science
Online product ratings are widely available on the Internet and are known to influence prospective buyers. An emerging literature has started to look at how ratings are generated and in particular how they are influenced by prior ratings. We study the social influence of prior ratings and, in particular, investigate any differential impact of prior ratings by strangers (“crowd”) versus friends. We find evidence of both herding and differentiation behavior in crowd ratings wherein users’ ratings…
Online product ratings are widely available on the Internet and are known to influence prospective buyers. An emerging literature has started to look at how ratings are generated and in particular how they are influenced by prior ratings. We study the social influence of prior ratings and, in particular, investigate any differential impact of prior ratings by strangers (“crowd”) versus friends. We find evidence of both herding and differentiation behavior in crowd ratings wherein users’ ratings are influenced positively or negatively by prior ratings depending on movie popularity. In contrast, friends’ ratings always induce herding. Further, the presence of social networking reduces the likelihood of herding on prior ratings by the crowd. Finally, we find that an increase in the number of friends who can potentially observe a user’s rating (“audience size”) has a positive impact on ratings. These findings raise questions about the reliability of ratings as unbiased indicators of quality and advocate the need for techniques to de- bias rating systems.

Blockbuster Culture's Next Rise or Fall: The Impact of Recommender Systems on Sales Diversity
Management Science
This paper examines the effect of recommender systems on the diversity of sales. Two anecdotal views exist about such effects. Some believe recommenders help consumers discover new products and thus increase sales diversity. Others believe recommenders only reinforce the popularity of already popular products. We find that some well known recommenders can lead to a reduction in sales diversity. Because common recommenders (e.g., collaborative filters) recommend products based on sales and…
This paper examines the effect of recommender systems on the diversity of sales. Two anecdotal views exist about such effects. Some believe recommenders help consumers discover new products and thus increase sales diversity. Others believe recommenders only reinforce the popularity of already popular products. We find that some well known recommenders can lead to a reduction in sales diversity. Because common recommenders (e.g., collaborative filters) recommend products based on sales and ratings, they cannot recommend products with limited historical data, even if they would be rated favorably. In turn, these recommenders can create a rich-get-richer effect for popular products and vice-versa for unpopular ones. That diversity can decrease is surprising to consumers who express that recommendations have helped them discover new products. In line with this, result two shows that it is possible for individual-level diversity to increase but aggregate diversity to decrease. Recommenders can push each person to new products, but they often push users toward the same products.. Third, we show how basic design choices affect the outcome, and thus managers can choose recommender designs that are more consistent with their sales goals and consumers’ preferences
