Introduction

Open Philanthropy (OP) is a major funder of work which aims to reduce AI risk. Consequently, studying OP’s past AI grants may be helpful to inform efforts to decrease AI risk.

Methods

OP’s AI grants were considered as those in OP’s grants database whose focus area is Potential Risks from Advanced AI[2]. The resulting 107 grants are in tab “Grants” of this Sheets. The grant amounts were adjusted for inflation based on data from in2013dollars (see tab “Inflation”), and are expressed in 2020-$.

The following linear regressions were studied for OP’s AI grants:

Results

The results were determined with this Colab. The linear regression parameters, data points, linear trends and respective 90 % confidence intervals are presented in the tables and figures below.

Linear regression of annual amount granted on year (2015-2021). The shaded region represents the 90 % confidence interval.

Discussion

The above analysis of OP’s AI grants indicates that:

The trend of the grant size cannot be meaningfully extrapolated forward, given the low coefficient of determination of 0.4 %.

The trend of the annual amount granted can be projected forward more meaningfully, given the higher coefficient of determination of 40 %. Assuming an annual inflation rate of 1.75 %[4], the annual amount granted is predicted to be:

    The focus areas of the downloadable CSV file of the database are not in agreement with those of the website. The latter were considered correct, as there were only 3 grants in the CSV with focus area “Potential Risks from Advanced AI”.

It seems like normality is violated on the first graph, have you tried taking a log transform or something?

Thanks for commenting!

I had not tested it, but your are kind of right! Applying the Shapiro-Wilk normality test to:

  • The grant size results in a p-value of 3*10^-20 (for the null hypothesis "the grant size follows a normal distribution"). 
  • The logarithm of the grant size results in a p-value of 0.3 (for the null hypothesis "the grant size follows a lognormal distribution").

So it looks like we can confidently reject the grant size following a normal distribution, but it could well follow a lognormal distribution. This aligns well with my expectations.
