The biased sample: why science should not be practised on friends
The biased sample is a kind of unrepresentative sample, either for quantitative reasons (as is the case with the too-small sample), or for qualitative ones, when its structure does not represent the structure of the real population that is the object of the research.
Judge and jury
I once served on a jury and, to my surprise, was voted foreman. The accused was charged with manslaughter, a serious crime with quite a harsh penalty; while driving an aged-care minivan filled with pensioners, he’d hit and killed a pedestrian. The defendant was a facility volunteer who had been taking a group of pensioners shopping. His vehicle collided with the deceased in...
How our friendships change throughout life
Because life in developed societies follows a more or less regular pattern, sociologists have managed to identify the age at which conditions are most conducive to forming a friendship. It's not that people who are not of this age are unable to form meaningful connections with other people, but at other ages, life takes us on different paths, without asking for our permission.
King, emperor, reformer
The Carolingian Renaissance must be understood as a "reform and reconfiguration of all peoples under the reign of Charles, with a view to creating a Christian territory in its institutional structures, moral conduct, and personal convictions."
Five lessons from the life of Dietrich Bonhoeffer
It takes a brave man to stand up to a dictator and perhaps an even braver one to stand up to his church. Dietrich Bonhoeffer has been held up as a hero of the cause of justice and equality, and a statesman of modern Christian theology. For some readers, these two things might not seem a natural fit. But for Bonhoeffer, the two...
Incurable faith
If we take an honest look around us and within ourselves, we discover that the gulf between the mentality of those who choose prayer over medical treatment and the essence of the Christian mindset is not as deep as it seems. But it remains a gulf nonetheless.
Conflict: It’s Everywhere
Conflict is everywhere: in our books, movies, TV shows. But every conflict is a mere shadow of the controversy that the entire world is embroiled in.
Pray as you can
I’m going to be honest with you. I find prayer really hard. If I had to give reasons for all my tears over the past few years, most of them have come during conversations with God.
Friedrich Nietzsche, Christianity, and Jesus of Nazareth
“I condemn Christianity; I bring against the Christian church the most terrible of all the accusations that an accuser has ever had in his mouth... The Christian church has left nothing untouched by its depravity; it has turned every value into worthlessness, and every truth into a lie, and every integrity into baseness of soul... the cross as the distinguishing mark of the...
Vaping: a plague disguised as a revolution
In developed countries, where the public debate on tobacco consumption has been so widespread that even those who had no desire for it were educated on the negative effects of smoking, the prevalence of this toxic habit dropped so drastically that it caused trouble for cigarette manufacturers.
Menstruation, a taboo still difficult to break even in 2021
Lack of access to menstrual hygiene is the fifth leading cause of death worldwide among women. In the world, 1 in 3 girls faces the impossibility of ensuring adequate hygiene during menstruation, and many others face sometimes fatal arbitrary limitations imposed by culture.
COVID-19: What we have (not) missed during the lockdown
Life in lockdown had an atypical rhythm and texture. While for some this upset their daily lives, for others it was an unexpected response to an unspoken need.
How false religious conspiracy theories came to abound
The documentary The Resurrection Tomb is based on James Tabor and Simcha Jacobovici’s book The Jesus Discovery[1] and resumes a controversial topic, also published in 2007, when a similar film was released.
Can’t get no motivation?
If you can’t get motivated, you aren’t alone. The people at Therapy Central recognise that many of us struggle with feelings of “nothing gets me going”, “I don’t care about anything” or “I just don’t care about getting out of bed”. In these situations, keeping motivated can be a chore.
In the arms of the coach
What can you do in the face of a terrible diagnosis, which condemns you to life in a wheelchair? What can you choose besides despair or resignation? Kayla chose to run.
