Skepticism Leads on Alien and AI Questions as Health Concerns Grow

Across science, expectations appear cautious rather than certain. People currently seem to think the United States is unlikely to confirm that aliens exist before the stated benchmark, and the same doubtful mood applies to confirmation by the later benchmark. These views do not establish what will happen. They show a strong lean toward no, with little visible support for an official confirmation.

Health expectations move in the opposite direction. Current views favor the possibility that U.S. measles cases will reach the stated benchmark. The mood is not uniform, but it strengthens as the question is framed at different levels. That makes public feeling more bullish on a measles increase than on alien confirmation.

AI and mathematics produce a more divided picture. People appear doubtful that OpenAI will announce another solved Millennium Prize Problem by the earlier benchmark. By the later benchmark, views split, with a slight pull toward yes in one reading and clearer support for yes in another. Expectations about additional problems solved by AI lean bearish overall, suggesting that excitement is mixed with doubt.

Climate expectations clearly favor a record-hot year, while other possible placements receive less support. Views on SpaceX having the largest IPO by market cap also lean negative. These themes show a sector where concern is strengthening in public health, confidence is limited in dramatic space and AI breakthroughs, and climate expectations remain unusually firm.
