Am I allowed to throw away *my* memories: does memory editing threaten human identity?

A paper has recently been published demonstrating that a previously learned fearful reaction can be weakened using a drug. The aim of the research is to ameliorate PTSD, post-traumatic stress disorder, where traumatic experiences cause an ongoing state of anxiety and stress reactions. In the media it of course became "drug can erase bad memories" and "Pill to erase bad memories: Ethical furore over drugs 'that threaten human identity'". Are we getting close to a memory eraser pill, and would it pose any ethical challenges?

Transparent brains: detecting preferences with infrared light

Researchers at University of Toronto have demonstrated that they can decode which of two drinks a test subject prefers by scanning their brains with infrared light. (Original paper here.) The intention is to develop better brain-computer interfaces for severely disabled people, but there are obvious other applications for non-invasive methods of detecting what people want. No doubt neuromarketers are drooling over the applications. But the threat to mental privacy might be a smaller problem than the threat of mistaken preferences.

Open source censorship

The struggle against child porn goes on. An Australian judge has ruled that a cartoon showing a character from The Simpsons engaged in sexual activity is child pornography. Australia is also trying to implement Internet filtering for the whole population, although the project has run into serious opposition. Meanwhile Wikipedia ended up 'censored' in the UK due to a page with the controversial cover of an album.

The most interesting aspect of the Wikipedia debacle is that the decision that led to the censorship was not made by any government authority but an industry-sponsored group, the Internet Watch Foundation. The IWF maintains a blacklist certain ISPs subscribe to, and users trying to reach a site on it will be sent a blank page. Is this censorship, and is this bad?

Hacking the spammers

Why is there spam? The simple answer is that "there is a sucker born every minute" and email is cheap enough to reach millions of potential suckers who might want to buy Viagra, sure-fire investments and fake Rolexes. A new study has discovered that it is enough with one response to every 12.5 million emails sent is enough to be profitable. The most interesting about the study was how it was done: by hacking the spammers own network. But is it OK to hack in order to understand spam?

Election ex machina: should voting machines be trusted?

When election of public officials through
public voting was instituted in the US,the framers of the constitution
had no inkling about how large the voting public would one day become. Beside logistical problems that
accidentally enfranchise goldfish and the many issues surrounding voter
registration a growing concern is the reliability of electronic voting
machines. As electronic voting machines are being installed, concerns about their reliability are being raised and legal battles ensue. In a Finnish election the system lost 2% of
all electronic votes. About 60% of American votes are cast on
paper ballots, but it might increase locally after problems with voting machines. The real fear is not that people might misvote due to misunderstandings or that votes might be miscounted, but that the machines themselves might be biased or easily tampered with. Can we trust the machines? Or are elections by their nature too messy for these problems to matter?

Should We Be Erasing Memories?

By S. Matthew Liao, Anders Sandberg, and Julian Savulescu

Scientists from the Medical College of Georgia in the US recently claimed to be able selectively to wipe out traumatic memories. These scientists experimented with mice and found that a particular protein plays a crucial role in the formation of memories. When they made the mice produce an excess of this protein, memories of painful events were completely eliminated.  Such research raises hope for treating conditions such as post-traumatic stress disorder (PTSD), in which painful memories become intrusive and damage an individual’s ability to live an ordinary life.  In theory, such memories could either have their emotional strength reduced or be blotted out altogether. In practice we are still some distance away from being able to achieve this, but it does not seem unreasonable to think that within the next decade we will be able to control the erasing of memory.

Protectionist deities vs. the economy of fun: ownership of virtual possessions

Do players in online games have a right to their virtual possessions? As discussed by Erin Hoffman in an essay the matter is a legal quagmire. Real money is involved, people have assaulted each other over virtual thefts, China now recognizes people’s right to their virtual property
while the US does not. As virtual worlds become ever bigger business
the legal issues surrounding virtual property will become more important – both directly in court, and indirectly in shaping what kinds of worlds will be profitable or even possible. But from an ethical standpoint, do we have a right to virtual property?
