01What it does

What Skeptic Society does

Mission

The skeptics society is a science education organization that makes available to its members a subscription to skeptic magazine, a quarterly publication that examines a wide variety of scientific and pseudoscientific controversies. The Skeptic Society also sponsors a monthly science lecture series at the california institute of technology in pasadena, ca, as well as hosts annual science conferences open to the public, and science education field trips, such as geology tours of southern california and the western united states. The society is dedicated to educating the public about controversial claims. We maintain a telephone referral service and a website so that schools, the press, and the general public can access our information. We tirelessly lend our scientific viewpoint to media coverage of a wide range of issues. In our print catalogue in skeptic magazine along with our online shop, we offer an extensive catalogue of scientific and skeptical books and audio and video recordings

As stated on its FY2024 Form 990.

The organization over time

Each line starts at 100 in 2017, so what you read is the shape rather than the size: 150 means half as much again as 2017, 50 means half. The number beside each label in the key is where it ended. The shaded band is where the middle 50% of its peers' revenue would sit, given their growth.

How it's funded, over time

Each bar is one year's revenue split into where it came from, and every bar is the same height — these are shares, not amounts, so a year that raised twice as much looks the same size. Hover a bar for the split.

03Who funds it

Who funds it, year by year

2017 → 2023: the base held at 5 funders, grant income rose $28k → $213k.

6 of 18 of your funders are donor-advised or pass-through sponsors (tagged DAF) — 38% of grant dollars received. That money is really individual donors directing a sponsor; the institutions to cultivate are the non-DAF funders.

From the IRS filings of SKEPTIC SOCIETY’s funders (the co-funder graph). Association, not causation. Trends are read to FY2023, the last fiscal year that has finished arriving. FY2024–FY2026 are still being filed and are shown unshaded; they do not move any figure on this page.

How concentrated its funding is

SKEPTIC SOCIETY leans on a few funders — its largest provides 54% of grant income and the top three 87%; half comes from just 1 funder.

the vertical line marks half of all grant income — 1 funder to its left

38% of the income these shares are computed over arrives through pass-through sponsors or from payers whose filings do not say what kind of payment it is. Concentration is still measured over all of it, because the money is real; what it does not support is a claim about how many institutions have chosen to fund SKEPTIC SOCIETY.

“Effective funders” = inverse Herfindahl index (1 / Σ shareᵢ²) — the number of equal-sized funders that would give the same concentration. Trends are read to FY2023, the last fiscal year that has finished arriving. FY2024–FY2026 are still being filed and are shown unshaded; they do not move any figure on this page.

How long its funders stay

27% of SKEPTIC SOCIETY's funders are still giving 3 years after their first grant; 44% give in more than one year at all.

first grant+1y+2y+3y+4y+5y+6y

Share of funders still giving k years after their first recorded grant, pooled across every acquisition cohort. A funder counts as retained in a year only if it made a grant that year. Measured to FY2023, the last fiscal year that has finished arriving — a funder cannot be counted as lapsed in a year most filers have not reached.

Funder states come from each funder’s own filing. $377k arriving through sponsors registered in 6 states is excluded from the map and the split above: a sponsor holds money on a donor’s behalf, so its registered address would place those dollars somewhere no donor need ever have been.

These figures are read directly from IRS Form 990 / 990-PF e-file XML: this organization’s own return for FY2025 (financials across 2017–2025), and the filings of 18 funders that report grants to it. “On record” means captured in the filings we have parsed — a funder that does not e-file, or whose grant detail is not itemized, will not appear. Filings run roughly 12–24 months behind. Trends on this page end at FY2023, the last fiscal year that has finished arriving; later years are shown and marked, and move no figure.
