The Build Journal

Short addresses/p1–/p4abhnv.in/p1 is the first paper, and so on.

Four Papers

Each paper is written in plain language for a general reader, with full references, and built to be explored: the claims come with figures you can operate, simulations you can run and, for the election paper, a live public ledger you can vote on.

No. 1 · April 2025 · abhnv.in/p1 Privacy and the data economy

Data for Sale

How your digital life fuels an unseen empire.

How personal data is collected, auctioned and sold, who buys it, what it costs the people it describes, and how the trade could be fixed. Sixteen figures you can operate, from a 110-millisecond ad auction to a broker pipeline.

No. 2 · June 2025 · abhnv.in/p2 Elections, cryptography and public trust

The Glass Ballot Box

Verifiable voting without giving up the secret ballot.

How an election can prove it counted correctly without revealing a vote: receipts that cannot be sold, risk-limiting audits, where blockchain helps and where it does not. Includes a live public ledger and a working prototype.

No. 3 · August 2025 · abhnv.in/p3 Decision science, a comparative study

Risk, Uncertainty and Decision-Making

How risk is defined, measured, felt and managed across frameworks.

Why no single definition of risk works everywhere: probability, expected utility, Bayesian reasoning, psychology and institutions compared on the same questions, with all 41 equations explained and simulations you can run.

No. 4 · October 2025 · abhnv.in/p4 AI, synthetic media and human judgment

The Outsourced Reality

What happens when machines both make the evidence and interpret it.

How synthetic media and AI assistants together change what counts as evidence and who does the judging: the liar's dividend, automation bias, provenance and watermarking, and the design of systems that keep people thinking.
